Association between Self-Perception of Chewing, Chewing Behavior, and the Presence of Gastrointestinal Symptoms in Candidates for Bariatric Surgery.

Given the changes in the digestive tract post-bariatric surgery, adapting to a new pattern of eating behavior becomes crucial, with special attention to the specifics of chewing mechanics. This study aimed to investigate the association between self-perception of chewing, chewing behavior, and the presence of gastrointestinal symptoms in preoperative patients undergoing bariatric surgery. Sixty adult candidates for bariatric surgery at a public hospital in Belém (Brazil) were analyzed. Participants predominantly exhibited unilateral chewing patterns (91.6%), a fast chewing rhythm (73.3%), a large food bolus (80%), liquid intake during meals (36.7%), and 41.7% reported that chewing could cause some issue. Significant associations were found between the perception of causing problems and chewing scarcity (p = 0.006), diarrhea (p = 0.004), absence of slow chewing (p = 0.048), and frequent cutting of food with front teeth (p = 0.034). These findings reveal a relationship between the perception of chewing problems and chewing scarcity, presence of diarrhea, and fast chewing.

Characteristics of carbohydrate counting practice associated with adequacy of glycated hemoglobin in adults with type 1 diabetes mellitus in Brazil.

Background: The Carbohydrate Counting (CC) is directly associated with achieving glycemic control by people with Type 1 Diabetes Mellitus (T1DM). Therefore, this study aims to analyze characteristics of the CC practice associated with the adequacy of glycated hemoglobin (HbA1c) in adults with T1DM in Brazil. Methods: The study was cross-sectional, carried out using an online form with questions about knowledge of CC, clinical, anthropometric, sociodemographic data, follow-up with health professionals and understanding of the concepts of CC. Pearson's chi-square test and binomial logistic regression analysis (p<0.05) were applied. Results: 173 adults participated, of which 57.2% had increased HbA1c (≥7%). Having the diabetes duration <10 years (p=0.006), performing the CC at lunch (p=0.040) and dinner (p=0.018), using specific applications to perform the CC (p=0.001), having learned to perform CC with a nutritionist (p=0.037) and knowing how to correctly define the concepts of food bolus (p=0.001), correction bolus (p<0.001) and insulin/carbohydrate ratio (p<0.001) was associated with having adequate HbA1c (<7%). Participants who were undergoing CC practice were 3.273 times more likely to have adequate HbA1c and participants with diabetes duration <10 years were 2.686 times more likely to have adequate HbA1c. Conclusion: It was concluded that variables transversal to CC favor adequate HbA1c values in adults with T1DM and that practicing CC and having a diabetes duration of less than 10 years are predictive factors of having adequate HbA1c.

Changes in Physical Activity Associated with Mental Health in People with Type 1 Diabetes during the COVID-19 Pandemic.

The social isolation carried out during the COVID-19 pandemic contributed to physical inactivity and impacted people's mental health, with physical activity being an important pillar in the treatment of Type 1 Diabetes Mellitus (T1DM). Thus, this study aims to verify whether there is an association between the perception of mental health and the practice of physical activity in individuals with T1DM during social isolation in the COVID-19 pandemic in Brazil. This was a cross-sectional study conducted in July 2020, with 472 adults with T1DM, using an online form to collect sociodemographic, mental health and physical activity data during social isolation. The Chi-Square test of independence was performed with adjusted residuals analysis (p < 0.05). A total of 51.3% of the participants remained sedentary or stopped doing physical activity during the period of social isolation. There was an association between being interested in performing daily activities (p = 0.003), not feeling depressed (p = 0.001), feeling slightly irritated (p = 0.006), having slight problems with sleep (p = 0.012) and practicing physical activity. There was also an association between maintaining physical activity and not feeling depressed (p = 0.017) and feeling very slightly irritated (p = 0.040). Adults with T1DM who practiced physical activity during the period of social isolation due to the COVID-19 pandemic showed better aspects of mental health.

Factors associated with grazing behavior in candidates for bariatric surgery at a hospital in the Amazon.

Blackground: To assess grazing behavior and associated factors in candidates for bariatric surgery monitored at a public hospital that is a reference in the care of people with severe obesity. Methods: Cross-sectional analytical study, with candidates for bariatric surgery of both genders, treated in a public hospital in the Amazon. To assess grazing behavior, the Repetitive Eating Questionnaire was used, and to investigate patterns of eating behavior, the Three Factor Eating Questionnaire was used, which assesses: Emotional Eating, Cognitive Restriction and Uncontrolled Eating. Sociodemographic information was obtained through self-report and the description of medication use through the medical record. Body mass index (BMI) was also calculated by measuring weight and height. The SPSS program, v. 21.0 was used. The study was approved by the Research Ethics Committee. Results: A total of 205 participants were evaluated, with a mean age of 37.5 ± 8.6 years, the majority (93.7%) being women and the majority (59.5%) was not also using medication to lose weight. About 66.3% of the participants had compulsive grazing. The factor with the highest score was cognitive restriction (p < 0.001). Individuals who used weight loss drugs had higher scores in the cognitive restriction factor (p = 0.015) and lower scores for uncontrolled eating (p = 0.008), compulsive grazing (p = 0.021) and non-compulsive grazing (p = 0.034). Conclusion: Linear regression showed that emotional eating and uncontrolled eating were predictors of both compulsive grazing and non-compulsive grazing behavior. It was observed that grazing behavior, cognitive restriction, emotional eating and uncontrolled eating are present and correlated in the studied patients. In addition, the use of weight loss drugs seems to help reduce dysfunctional eating behaviors in patients with severe obesity.

Associations between Orthorexia Nervosa, Body Self-Image, Nutritional Beliefs, and Behavioral Rigidity.

Possible correlations between orthorexic self-reports, unhealthy nutritional beliefs, behavioral rigidity related to following rules, and distortion of body self-image were investigated. In total, 246 university students of both sexes, from different areas of knowledge, answered a sociodemographic form, the Ortho-15, the Body Shape Questionnaire, the Rigidity Scale, and a Nutritional Beliefs Form. Orthorexic self-reports were observed in 73 men and 106 women. A positive correlation was found between females and orthorexic self-reports (p = 0.036), and severe distortion of body self-image (p = 0.002) and between the latter, the behavioral rigidity scale (p2 = 0.189; p = 0.001), and female sex (p2 = 0.245; p < 0.000). In the logistic regression, women were 1.83 times more likely to present orthorexic behaviors than men. The creation of prevention and treatment strategies aimed at women is suggested and it recommended that studies investigating whether the presence of orthorexic self-reports is a risk factor for the development of eating disorders are carried out.

Correlation between Anxiety Symptoms and Perception of Quality of Life in Women with More Than 24 Months after Undergoing Bariatric Surgery.

Purpose: To analyze the correlation between anxiety symptoms and perceived quality of life in women more than 24 months after undergoing bariatric surgery. Methods: Cross-sectional, descriptive and analytical study, carried out with women who underwent bariatric surgery after at least 24 months. To assess the level of anxiety symptoms, the Beck Inventory was used and to assess the perception of quality of life, the Item Short Form Healthy Survey was applied. Results: Of the 50 participants, 36.0% had reports indicative of moderate symptoms and 64.0% had severe symptoms of anxiety. The domains of quality of life that correlated with better perception were pain (p < 0.001), functional capacity (p = 0.013), general health status (p = 0.018), social aspects (p < 0.001), and mental health (p < 0.001). In linear regression, a significant inverse correlation was found between the general emotional component of quality of life and anxiety score (ß = −0.546; CI −1.419; −0.559; p < 0.001) and between the general physical component of quality of life and anxiety score (ß = −0.339; CI −0.899; −0.131; p = 0.010), both independent of weight regain and surgery time. Conclusions: It was observed that moderate to severe anxiety symptoms seem to interfere with the perception of quality of life, regardless of weight regain and surgery time.

Effects of Justifications Presented in Children's Stories on Students Following Descriptive Rules / Efeitos de Justificativas Apresentadas em Histórias Infantis sobre o Seguir Regras Descritivas por Alunos / Efectos de Justificaciones, Presentadas en Historias Infantiles, sobre el Seguir Reglas Descriptivas por Alunos

Abstract The present study investigated the justifications' effects, presented in children's stories, on the installment and maintenance of targeted behaviors: to copy, to answer and to present the exercise and competitive activities. Four children were exposed to three phases. In Phase 1, baseline, the registration of the target behaviors' events was made. Phase 2 was constituted of six steps. In each step, at the beginning, the experimenter would read a children's story with Type 5 justification that indicated the advantages of studying mathematics in the Steps 1, 2 and 5, and portuguese in the Steps 3, 4 and 6. Then, the teacher would write the exercise on the board and would request the students to copy, to answer and to present the exercise finished. Afterwards, the registration of the target behaviors' events was made for 30 minutes. In Phase 3 (Follow-up), fulfilled two months after Phase 2, it wasn't presented stories with justifications. The registration of targeted behaviors was made. In Phase 2, it occurred higher duration of activities to copy and to answer the exercise and lower duration of competitive activities. In Phase 3, occurred the opposite. It's suggested that, besides justifications, other variables contributed to maintain the observed behaviors.

Resumo O estudo investigou os efeitos de justificativas, apresentadas em histórias infantis, sobre a instalação e manutenção dos comportamentos alvos: copiar, responder e apresentar o exercício e atividades concorrentes. Quatro crianças foram expostas a três fases. Na Fase 1, linha de base, era feito o registro de eventos dos comportamentos alvos. A Fase 2 era constituída de seis passos. Em cada passo, no início, a experimentadora lia uma história infantil com justificativa do Tipo 5 que indicava as vantagens de se estudar matemática, nos Passos 1, 2 e 5, e português, nos Passos 3, 4 e 6. Depois, a professora escrevia o exercício na lousa e pedia para os alunos copiarem, responderem e apresentarem o exercício respondido. Em seguida, era feito um registro de eventos dos comportamentos alvos durante 30 min. Na Fase 3 (Follow-up), realizada dois meses após a Fase 2, não eram apresentadas histórias com justificativas. Era feito um registro de eventos dos comportamentos alvos durante 30 min. Na Fase 2, houve elevação da duração das atividades de copiar e responder o exercício e diminuição da duração das atividades concorrentes. Na Fase 3, ocorreu o inverso. Sugere-se que, além de justificativas, outras variáveis contribuíram para manter os comportamentos observados.

Seleção do Comportamento por Justificativas Constituintes de Regras / Selección de Comportamientos por Justificaciones Constituyentes de Reglas / Selection of Behavior by Justifications as Constituent of Rules

Resumo Considerando que a distinção entre os efeitos de estímulos constituintes de regras e de contingências de reforço na determinação do comportamento não está clara, o presente estudo teve como objetivo tentar esclarecer essa distinção por meio da apresentação da teoria do Controle por Justificativas e por Consequências Imediatas (Teoria TJC). Essa teoria, baseada em resultados experimentais, é constituída dos seguintes conceitos, formulados em estudos prévios: Propriedade formal de estímulos verbais; regras; comportamento; ambiente social; ambiente social verbal; ambiente social não verbal; consequências imediatas; consequências futuras; justificativas; justificativas dos Tipos 1, 2, 3, 4 e 5; aprovação ou desaprovação por justificativas e por consequências imediatas; regras com e sem justificativas relatadas; eventos futuros passíveis e não passíveis de serem contatados; e, histórias do ouvinte de controle: (a) por consequências imediatas diferenciais, (b) por justificativas diferenciais, e (c) pela interação entre justificativas e consequências imediatas diferenciais, para seguir e para não seguir regra. A Teoria postula o estabelecimento de limites entre o que deve ser atribuído a funções de estímulos constituintes de regras e entre o que deve ser atribuído a funções de estímulos constituintes de contingências de reforço. Postula também que justificativas podem selecionar comportamento.

Resumen Considerando la distinción entre los efectos de las reglas constituyentes de estímulos y contingencias de reforzamiento en la determinación del comportamiento no es claro, este estudio tuvo como objetivo tratar de aclarar esta distinción mediante la presentación de la teoría de Control por Justificaciones y por Consecuencia. In mediatas (Teoría TJC). Esta teoría, basándose en los resultados experimentales, se compone de los seguientes conceptos, formulados en estudios anteriores: propiedad formal de estímulos verbales; reglas; comportamiento; entorno social verbal; entorno social no verbal; consecuencias inmediatas; consecuencias futuras; justificaciones; justificaciones de los Tipos 1, 2, 3, 4 y 5; aprobación o desaprobación por justificaciones y por consecuencias inmediatas; reglas con y sin justificaciones reportadas; eventos futuros con o sin la posibilidad de ser contactados; y, historias del oyente, de control: (a) por consecuencias inmediatas diferentes, (b) por justificaciones diferentes, y (c) por la interacción entre justificaciones y consecuencias inmediatas distintas, para seguir y para no seguir la regla. La teoría postula el establecimiento de límites entre lo que debe ser asignado a funciones de estímulos constituyentes de reglas y entre lo que debe ser asignado a funciones de estímulos contituyentes de contingencias de refuerzo. También postula que las justificaciones pueden seleccionar el comportamiento.

Abstract Considering that the distinction between the effects of stimuli that are constituent of rules and of reinforcement contingencies in the determination of behavior is not clear, this study attempts to clarify such a distinction by the presentation of the Theory of Control by Justifications and by Immediate Consequences (TJC Theory). This theory, grounded in experimental results, comprises the following concepts, as defined in previous studies: formal properties of verbal stimuli; rules; behavior; social environment; verbal social environment; nonverbal social environment; immediate consequences; justifications; justification Types 1, 2, 3, 4, and 5; approval or disapproval by justification and by immediate consequences; rules with and without reported justifications; future events that may or may not be contacted; and control histories of the listener by (a) immediate differential consequences, (b) differential justifications, and (c) the interaction between justifications and immediate differential consequences for following rules and for not following rules. The theory postulates the establishment of limits between what should be attributed to functions of stimuli as constituent of rules and what should be attributed to functions of stimuli as constituent of reinforcement contingencies. TJC Theory also postulates that justification can select behavior.

Efeitos de Histórias do Ouvinte sobre o Seguimento de Regras Discrepantes das Contingências / Efectos de Historias del Oyente acerca del Seguimiento de las Reglas Discrepantes de las Contingencias / Effects of Listener's Histories on Following Rules that are Discrepant to Contingencies

Resumo Objetivando testar proposição sobre as características críticas da história do ouvinte que podem interferir no seguir regra discrepante, oito universitários foram expostos a um procedimento de escolha segundo o modelo. A tarefa era apontar para os três estímulos de comparação em sequência. Na Fase 1, nenhuma sequência era instruída ou reforçada. A Fase 2 era iniciada com a regra correspondente. As contingências da Fase 2 eram alteradas, sem sinalização, na Fase 3, e as contingências da Fase 3 eram mantidas inalteradas na Fase 4, iniciada com a regra discrepante. Dos oito participantes, seis apresentaram um comportamento independente e dois apresentaram um comportamento dependente de suas consequências imediatas na Fase 3. Dos seis participantes que apresentaram um comportamento independente das consequências imediatas na Fase 3, quatro seguiram a regra discrepante na Fase 4. E dos dois participantes que apresentaram um comportamento dependente das consequências imediatas na Fase 3, todos abandonaram o seguimento da regra discrepante na Fase 4. Sugere-se que a dependência e a independência do comportamento às suas consequências imediatas, antes da apresentação da regra discrepante, são variáveis críticas da história do ouvinte que podem ser utilizadas para se prever a manutenção, ou não, do seguimento subsequente de regra discrepante.

Resumen Con objetivo de probar proposición acerca de variables que pueden interferir acerca del seguimiento de regla, ocho estudiantes universitarios fueron expuestos a un procedimiento de elección de acuerdo con el modelo. La tarea era señalar a los tres estímulos de comparación en secuencia. En Fase 1, ninguna secuencia era enseñada o reforzada. Fase 2 comenzaba con la regla correspondiente a las contingencias programadas. Contingencias de Fase 2 eran cambiadas, sin señalización, en Fase 3, y contingencias de Fase 3 eran conservadas en Fase 4, comenzada con la regla discrepante de las contingencias. De los ocho participantes, seis presentaron un comportamiento independiente y dos presentaron un comportamiento dependiente de sus consecuencias inmediatas en Fase 3. De los seis participantes que presentaron un comportamiento independiente de las consecuencias inmediatas en Fase 3, cuatro seguirán la regla discrepante en Fase 4. Y de los dos participantes que presentaron un comportamiento dependiente de las consecuencias inmediatas en Fase 3, todos abandonaran el seguimiento de regla discrepante en Fase 4. Se sugiere que dependencia y independencia del comportamiento a sus consecuencias inmediatas son variables críticas de la historia del oyente que pueden ser usadas para predicción del mantenimiento, o no, del seguimiento subsiguiente de regla.

Abstract Testing proposition by aiming on the listener's history critical characteristics that may meddle on the discrepant-rule following, eight college students were exposed to a matching to sample procedure. The task was to point to the three comparison stimuli in a sequence. In Phase 1 no sequence was instructed or reinforced. Phase 2 begun with the rule corresponding to the contingencies. Contingencies effective in Phase 2 were shifted without warning in Phase 3. Contingencies in Phase 3 were kept unchanged in Phase 4, which started with the presentation of a discrepant rule. Six out of eight participants showed an independent behavior and two out of eight showed a dependent behavior from its immediate consequences in Phase 3. From those six out of eight participants showing an independent behavior, four managed to follow the discrepant-rule in Phase 4. And from the latter two out of eight showing a dependent behavior, all of them abandoned the discrepant-rule following in Phase 4. It is suggested that the behavior's dependence and independence to its immediate consequences, before the discrepant-rule presentation, are critical variables of the listener's history that may be used to foresee maintenance, or not, from the subsequent discrepant-rule following.

Controle por regras: efeitos de perguntas, propriedades formais de regras e esquemas de reforço / Control by rules: effects of questions, formal properties of rules and reinforcement schedules

Com o objetivo de investigar os efeitos de variáveis sobre o seguimento de regras, 24 estudantes universitários foram expostos a um procedimento de escolha de acordo com o modelo. A tarefa era apontar para os estímulos de comparação em sequência. Na Fase 1, a sequência correta era estabelecida por reforço diferencial em esquema de reforço contínuo. Nas Fases 2 e 3, as contingências de reforço eram mantidas inalteradas, enquanto as regras discrepantes de tais contingências (sugestão e ordem) eram manipuladas. Nas Condições 1 e 2, nas Fases 2 e 3, eram apresentadas a sugestão e a ordem, respectivamente. Nas Condições 3 e 4, era o inverso. Apenas na Fase 1 das Condições 1 e 3 eram feitas perguntas acerca do comportamento que produz reforço. 100% dos participantes não seguiram a sugestão e 60% não seguiram a ordem. Os resultados sugerem que a história do comportamento alternativo ao especificado pela regra, justificativas e perguntas são variáveis que podem interferir no comportamento de seguir regras discrepantes das contingências de reforço. Os resultados têm implicações para o esclarecimento das funções das contingências de reforço e de regras na explicação do comportamento.

Aiming the investigation of the effects of some variables on rule following, 24 college students were submitted to a matching-to-sample procedure, with the task of pointing to the comparison stimuli in sequence. In Phase 1 the correct sequence was established by differential reinforcement in continuous reinforcement schedule. In Phases 2 and 3 the reinforcement contingencies were kept unchanged, and meanwhile rules (suggestion and mand) discrepant of the contingencies were manipulated. In Conditions 1 and 2, Phases 2 and 3 suggestion and mand were presented in this sequence. In Conditions 3 and 4 the presentation order was reversed. Questions concerning why the behavior was reinforced were presented only in Phase 1 of Conditions 1 and 3. Hundred percent participants did not follow the suggestion, 60% did not follow the mand. Results indicate that the history of alternative behavior to the specified by the rule, justifications, and questions may interfere with the discrepant-to-the-contingencies rule-following, and implications for the comprehension of the functions of the reinforcement contingencies and rules in the explanation of behavior.

Efeitos de histórias experimentais e de justificativas sociais sobre o comportamento de seguir regras / Effects of experimental stories and social justifications on rule following behavior

Este estudo avaliou o efeito de justificativas sobre o comportamento de seguir regras, quando foi construída uma história de reforço para não seguir regra. Dez crianças foram expostas a um procedimento de escolha segundo o modelo, cuja tarefa era tocar um de dois estímulos de comparação na presença de um estímulo contextual. Nas Condições I e II, as Fases 1, 2 e 4 eram iniciadas com a apresentação de instruções discrepantes das contingências programadas, cujo comportamento de segui-las produzia perda de fichas. Na Fase 3 era apresentada uma instrução correspondente com uma justificativa para seguir a instrução que produzia perda de fichas. A Condição I diferia da Condição II apenas com relação ao tipo de justificativa apresentada na Fase 3. Na Condição I era apresentada uma justificativa para ajudar crianças carentes e na Condição II uma justificativa que envolvia a aprovação do experimentador. O comportamento de nove dos 10 participantes ficou sob o controle da história de reforço para o não seguir instrução e das consequências imediatas produzidas pelo comportamento de não seguir instruções; o comportamento de um participante ficou sob o controle da justificativa para seguir a instrução correspondente.

The effect of justifications on rule-following behavior after a history of reinforcement for not following rules was evaluated. Ten children were submitted to a matching to sample procedure such as the task was to touch one of two comparison stimuli in the presence of a contextual stimulus. In Conditions 1 and 2, the Phases 1, 2, and 4 begun with the presentation of an instruction that was discrepant to the contingencies; following the rule lead to the loss of tokens. In Phase 3 it was presented an instruction corresponding to the contingencies, with a justification for following the instruction that lead to the loss of tokens. The difference of Conditions 1 and 2 was only regarding to the justification presented in Phase 3. The justification presented in Condition 1 was "to help poor children" and in Condition 2 a justification regarding experimenter's approval. The behavior of 9 out of 10 participants was under control of the experimental history of reinforcement for not following instructions and of the immediate consequences produced by the behavior of not following instructions; the behavior of one participant was under control of the justification for following the corresponding instruction.

Variáveis que podem interferir no seguir regras de participantes flexíveis e inflexíveis / Variables which may interfere in following rules by flexible and inflexible participants

Com o objetivo de avaliar o efeito de histórias pré-experimentais sobre o seguir regras, 16 estudantes universitários foram expostos a um procedimento informatizado de escolha segundo o modelo. A tarefa era apontar cada um dos três estímulos de comparação em sequência. Oito participantes, quatro flexíveis e quatro inflexíveis, foram submetidos a cada uma das duas condições de quatro fases. Na Fase 1, a sequência correta era estabelecida por contingências. Reforço para a emissão da sequência correta foi mantido durante as três fases - na Condição 1, o programa de reforço contínuo (CRF) e na Condição 2, a relação fixa de quatro (FR4). Em ambas as condições, a Fase 2 começou com a apresentação de uma regra discrepante, a Fase 3 começou com uma regra correspondente, e Fase 4 começou com uma regra discrepante. Seguindo a regra discrepante não produziu o reforço programado, mas seguindo a regra produzida correspondente reforço. Na Condição 1 (CRF) , os 8 participantes deixaram de seguir a regra discrepante, independentemente de serem ßexíveis ou inßexíveis. Na Condição 2 (FR4), os inßexíveis seguiram e os ßexíveis deixaram de seguir a regra discrepante. Sugere-se que os efeitos de histórias pré-experimentais são modulados por variáveis atuais.(AU)

Aiming to evaluate the effect of pre-experimental histories on rule-following, 16 college students were submitted to a computerized matching-to-sample procedure. The task was to point to each of three comparison stimuli in sequence. Eight participants, 4 flexible and 4 inflexible, were allocated to each of two four-phase conditions. In Phase 1, the correct sequence was established by contingencies. Reinforcement to the emission of the correct sequence was maintained during the following three phases - in Condition 1, the continuous reinforcement schedule (CRF), and in Condition 2, the fixed-ratio 4 (FR4). In both conditions, Phase 2 started with the presentation of a discrepant rule, Phase 3 started with a corresponding rule, and Phase 4 started with a discrepant rule. Following the discrepant rule did not produce the programmed reinforcement, but following the corresponding rule produced reinforcement. In Condition 1 (CRF), the 8 participants, flexible and inflexible, stopped following the discrepant rule. In Condition 2 (FR 4), the inflexible participants kept following the discrepant rule and the flexible ones stopped following it. It is suggested that the effects of pre-experimental histories are modulated by present variables.(AU)

O estudo investigou os efeitos de perguntas e respostas às perguntas sobre o seguir regras por 15 crianças, distribuídas em três grupos. Nas fases 1 e 3 era medido o comportamento de doar bombons e na Fase 2 era contada uma história com uma regra especificando que quem doa alimentos tem amigos para brincar. Os grupos diferiram na Fase 2: para o Grupo 1 não eram feitas perguntas; para o Grupo 2 eram feitas perguntas ao longo da história; e para o Grupo 3 eram feitas perguntas ao final da história. Dos participantes que não doaram bombons na Fase 1 dos grupos 1, 2 e 3, 50%, 100% e 100%, respectivamente, doaram na Fase 3. Sugere-se que perguntas e respostas podem interferir na ocorrência do seguir regras.(AU)

The effects of questions and answers to questions upon rule following were investigated with 15 children, distributed in three groups. In phases 1 and 3, the number of candies given was measured; in Phase 2, a story was told with a rule specifying that who gives goodies has friends to play. The groups differed in Phase 2: for Group 1, the experimenter did not ask questions; for Group 2, questions were asked during the story telling; and for Group 3, questions were asked at the end of the story. From those participants who did not give candies in Phase 1 of groups 1, 2 e 3, 50%, 100% and 100%, respectively, did so in Phase 3. The results of this study suggest that questions and answers interfere with the occurrence of rule following.(AU)

Efeitos de instruções preliminares sobre o seguimento de regras / Effects of general instructions on rule following

O presente estudo teve como objetivo testar os efeitos de diferentes instruções preliminares sobre o seguimento de regras. Dezoito estudantes universitários foram expostos a um procedimento modificado de escolha de acordo com o modelo e distribuídos em três grupos, que diferiram quanto às instruções preliminares recebidas (completa, sem trechos sobre materiais ou sem trechos sobre conseqüências). Os participantes de cada grupo foram divididos em duas condições experimentais, em que instruções correspondentes ou discrepantes foram apresentadas. Os resultados mostraram que a ausência de trechos sobre materiais dificulta a realização da tarefa e a ausência de trechos sobre as conseqüências diminui a variação de respostas, porém todos os participantes que realizaram corretamente a tarefa seguiram tanto instruções correspondentes quanto discrepantes.(AU)

The present work had as objective to test the effects of different general instructions on rule following. Eighteen college students were exposed to a modified match-to-sample task and divided in three groups, which differed in the presentation of preliminary instructions (complete, without passages about materials or without passages about consequences). Subjects of each group were divided in two experimental conditions, in which accurate and inaccurate instructions were presented. Results showed that absence of sections about materials in the instructions complicates the learning task while absence of sections about consequences decreases the variety of responses. Notwithstanding, all subjects that performed the task correctly followed both accurate and inaccurate instructions.(AU)

Efeitos de manipulações de propriedades formais de estímulos verbais sobre o comportamento / Effects of manipulation of formal properties of verbal stimuli on behavior

Objetivando avaliar os efeitos de estímulos antecedentes verbais sobre o comportamento, 24 estudantes universitários foram expostos a um procedimento de escolha segundo o modelo; a tarefa consistia em apontar para cada um dos três estímulos de comparação. O comportamento correto era reforçado em razão fixa 6. Na Condição 1, a ordem de apresentação dos estímulos nas Fases 2, 3, 4 e 5 era: instrução correspondente, instrução mínima, pergunta correspondente, pergunta mínima, respectivamente. As oito condições diferiam quanto à ordem de apresentação das instruções e perguntas. A instrução e a pergunta correspondente estabeleceram o comportamento correto em 95 por cento e 33 por cento dos casos, respectivamente. A instrução e a pergunta mínima não estabeleceram o comportamento correto. Os resultados têm implicações para as definições de regras.(AU)

Aiming to investigate the effects of antecedent verbal stimuli on behavior, twenty-four students were exposed to a match to sample procedure. The task consisted of pointing out to each of three comparison stimuli. The correct behavior was reinforced in fixed ratio 6. In Condition 1, the order of the presentation of the stimuli at the beginning of phases 2, 3, 4 and 5 was: corresponding instruction, minimal instruction, corresponding question, minimal question, respectively. The eight conditions differed only in the order in which the verbal stimuli were presented. The corresponding stimuli and corresponding question established the correct behavior in 95 percent and 33 percent of the cases, respectively. The minimal stimuli didn't establish the correct behavior. The results have implications on the defining of rules.(AU)
