The Effects of Positive Versus Negative Self-Talk on Vertical Jump in Soccer Players: The Moderating Role of Need for Cognition.

The current study analyzed the effects of positive versus negative self-talk on physical performance in soccer players from a multiprocess approach. We operationalized the process distinction using the need-for-cognition (NC) construct. Thus, NC was measured and self-talk (i.e., positive vs. negative) was manipulated between participants (i.e., 126 soccer players, age 18 years or older, who were competing in national, regional, or local competitions). Physical performance was assessed by a vertical-jump test. According to hypothesis, regression analyses indicated that positive versus negative self-talk influenced physical performance to a greater extent for high-NC individuals than for low-NC individuals. Specifically, among high-NC soccer players, relative to baseline, positive self-talk produced greater physical performance in the vertical-jump test than negative self-talk. In contrast, among low-NC soccer players, no difference was found between positive and negative self-talk on physical performance. These results supported the moderating role of NC.

The meta-cognitive role of thought morality in attitude change and behavioural intentions related to doping.

Prior research has examined the relationships between morality, attitudes, and intentions related to doping predominantly via correlational studies based on the theoretical frameworks provided by extensions to the theory of planned behaviour, and the social cognitive theory of moral thought and action. In contrast, the present study experimentally analysed a psychological process (i.e., self-validation) through which thought morality can influence attitudes and intentions. Two hundred and forty-two participants (122 males and 120 females) were randomly assigned to read a message either against or in favour of legalising several doping behaviours in sports, then listed their thoughts regarding that proposal. Next, they were randomly assigned to perceive their thoughts as either moral or immoral, then indicated the extent to which they considered their thoughts as valid. Finally, participants reported their attitudes and intentions regarding the legalisation proposal. As hypothesised, the anti-legalisation (vs. pro-legalisation) message produced more unfavourable thoughts and attitudes, as well as lower intentions to support the legalisation proposal and engage in banned behaviours if legalised in sport. Most importantly, the effects of message direction on attitudes and intentions were greater for participants in the moral (vs. immoral) thought condition. Furthermore, changes in attitudes were consistent with a self-validation process.

A meta-cognitive approach to doping in sports: The effects of thought validation on attitudes related to doping.

To better understand doping-related attitude change, it is important to consider not only the amount of thinking (i.e., elaboration) done by message recipients, but also the favourability of their thoughts in response to the proposal, as well as the perceived validity in their thoughts. The main goal of the present study was to analyse the effects of a meta-cognitive process (i.e., thought validation) on attitudes related to doping. Thus, we randomly assigned participants to read a message either against or in favour of legalising several doping behaviours. Participants listed their thoughts regarding the proposal and indicated the perceived validity in their thoughts, then reported their attitudes. As hypothesised, the message against legalisation elicited more unfavourable thoughts and attitudes than the message in favour of legalisation. Most relevantly, the effects of the message direction on attitudes were greater for participants with higher (vs. lower) levels of thought validity. Furthermore, consistent with the thought validation process, results revealed that thought favourability was a better predictor of attitudes for participants with higher (vs. lower) perceived thought validity, indicating that perceiving one's thoughts as valid plays an important role in persuasion. These findings provide novel insights for research and interventions regarding doping in sports.

Changing attitudes and intentions related to doping: An analysis of individual differences in need for cognition.

Research has shown that athletes' attitudes towards the use of banned performance-enhancing substances are reliable predictors of their intentions to use these substances, which in turn can be relevant predictors of their actual doping behaviours. Despite the important role played by attitudes and intentions in doping, research analysing how to change those attitudes and intentions is relatively scarce. The present study examined how individual differences in Need for Cognition (NC, Cacioppo & Petty, 1982) influenced doping-related attitude change and subsequent behavioural intentions. Participants were randomly assigned to read a persuasive message either against or in favour of legalising the use of several banned substances, including anabolic androgenic steroids (AAS) and Erythropoietin (EPO). In addition, participants completed the NC scale, and finally reported their attitudes and behavioural intentions regarding the legalisation proposal. As hypothesised, results showed that participants who received an anti-legalisation message had significantly more unfavourable attitudes towards the proposal than participants who received a pro-legalisation message, regardless of NC. However, as predicted, NC moderated the relationship between individuals' attitudes and their intentions. That is, high-NC participants showed greater attitude-intention correspondence than low-NC participants.

The Effects of Overt Head Movements on Physical Performance After Positive Versus Negative Self-Talk.

Research on self-talk has found that what athletes say to themselves influences their performance in sport settings. This experiment analyzed the relationship between positive and negative self-talk and physical performance in light of another variable: overt head movements. Participants were randomly assigned to first generate and then listen to either positive or negative self-statements. They were then randomly assigned to nod (up and down) or to shake (side to side) their heads while being exposed to the self-statements they had previously generated. Finally, physical performance was assessed using a vertical-jump task, a squat test, and a deadlift task. As expected, positive self-statements led to better performance than negative self-statements in 2 out of 3 physical tasks. Most relevant, the main effect of self-talk was significantly qualified by head movements. Consistent with the authors' hypothesis, athletes' self-statements were significantly more impactful on physical performance in the head-nodding condition than in the head-shaking condition.

The Effects of Elaboration on the Strength of Doping-Related Attitudes: Resistance to Change and Behavioral Intentions.

This experiment analyzed whether attitudes toward the legalization of several doping behaviors would resist change and predict behavioral intentions when they were initially formed through thoughtful (i.e., high elaboration) versus nonthoughtful (i.e., low elaboration) processes. Participants were randomly assigned first to a persuasive message either against or in favor of the legalization, which they read with relatively high or low degrees of deliberative thinking. Attitudes and intentions regarding legalization were assessed following that message. Next, each participant received a second message that was opposed to the first one, serving as an attack against the attitude that participants had just formed. Finally, attitudes were again assessed. As hypothesized, participants showed greater attitude-consistent intentions when they formed their initial attitudes through thoughtful (vs. nonthoughtful) consideration of the first message. Moreover, the second message resulted in greater resistance to attitude change when participants formed their initial attitudes through thoughtful (vs. nonthoughtful) processes.

The interplay between self-talk and body posture on physical performance: Analyzing a moderated serial multiple mediation model.

Prior research has shown that non-verbal behavior (e.g., overt head movements) can moderate the effects of positive and negative self-talk on physical performance. In the current studies, we aimed to extend existing research on self-talk by examining a different non-verbal behavior (i.e., body posture), as well as specifying some conditions under which body posture can interact with self-talk on physical performance from the Self-Validation Theory perspective. Most importantly, we proposed and tested a moderated serial multiple mediation model. In Studies 1 and 2, self-talk (i.e., positive vs. negative) and body posture (i.e., upright vs. slumped) were manipulated between participants. In Study 1, soccer players performed slalom and dribbling tests. In Study 2, athletes performed a push-up test. We hypothesized and found that positive (vs. negative) self-talk influenced physical performance to a greater extent for participants in the upright posture (i.e., validating) condition than for participants in the slumped posture (i.e., invalidating) condition. Furthermore, Study 3 was designed to analyze a moderated serial multiple mediation model. In this third study, self-talk was positive, body posture was manipulated, and the meaning of body posture was measured as a moderator. Results supported the proposed model, identifying the perceived validity of self-statements (i.e., the self-validation mechanism) and self-efficacy as serial mediators. That is, the meaning (i.e., validity-invalidity) moderated the effects of body posture on athletes' physical performance in a pull-up test, through the indirect effects of the perceived validity of self-statements and self-efficacy. Implications for self-talk research and application are discussed.

Changing Attitudes About a Pro-Environmental Proposal Concerning Solar Power: The Self-Validating Role of Ingroup Versus Outgroup Sources.

BACKGROUND: In this study, we examined whether a persuasive message in favor of a pro-environmental proposal could influence attitude change through a self-validation process when individuals were told that the source of the proposal belonged to their ingroup (vs. their outgroup). METHOD: Participants read a message that advocated for the use of solar power. Immediately following the message, participants were asked to list their thoughts regarding the persuasive proposal. A thought favorability index was created for each participant. Following the thought-listing task, participants received the experimental manipulation (i.e., ingroup vs. outgroup source) based on the minimal group paradigm, after which they reported their attitudes towards the proposal. RESULTS: A regression analysis showed the predicted interaction between thought favorability and type of source (i.e., ingroup vs. outgroup) on attitudes towards the solar power proposal. According to our expectations, thought favorability was a better predictor of attitudes for participants in the ingroup (vs. outgroup) source condition. CONCLUSIONS: Attitudes can be polarized as a function of ingroup versus outgroup differentiation through a self-validation process.

Treating thoughts as material objects can increase or decrease their impact on evaluation.

In Western dualistic culture, it is assumed that thoughts cannot be treated as material objects; however, language is replete with metaphorical analogies suggesting otherwise. In the research reported here, we examined whether objectifying thoughts can influence whether the thoughts are used in subsequent evaluations. In Experiment 1, participants wrote about what they either liked or disliked about their bodies. Then, the paper on which they wrote their thoughts was either ripped up and tossed in the trash or kept and checked for errors. When participants physically discarded a representation of their thoughts, they mentally discarded them as well, using them less in forming judgments than did participants who retained a representation of their thoughts. Experiment 2 replicated this finding and also showed that people relied on their thoughts more when they physically kept them in a safe place-putting their thoughts in their pockets-than when they discarded them. A final study revealed that these effects were stronger when the action was performed physically rather than merely imagined.

Spanish Adaptation of the Need for Affect Questionnaire (NAQ and NAQ-S).

BACKGROUND: Need for affect (NA) refers to individual differences in the motivation to approach or avoid emotion-inducing situations and activities. Prior research has demonstrated that NA is a relevant construct for understanding psychological processes related to affect. The present study aimed to adapt and validate the English version of the Need for Affect Questionnaire (NAQ), as well as the short version (i.e., the NAQ-S), to Spanish. We examined evidence of validity and reliability in the NAQ and NAQ-S scores. METHOD: Study 1 ( N = 416) analyzed the psychometric properties of scores from the Spanish adaptation of the NAQ, as well as the relationships with measures of other relevant psychological constructs. Study 2 ( N = 118) tested the validity and reliability of scores from the Spanish adaptation of the NAQ-S. RESULTS: We found two main factors (i.e., Emotion Approach and Emotion Avoidance), and the internal consistency of both the NAQ and the NAQ-S scores, as well as their test-retest reliability, were adequate. Relationships with other measures were in line with prior research, providing positive evidence of concurrent validity. CONCLUSIONS: Scores from both instruments showed validity and reliability, so should be considered in future research related to NA.

Mental, physical, and phychophysiological responses to FFP2/N95 face mask during HIIT in active women.

Training systems based on high-intensity interval training (HIIT) have experienced great influence in recent years within the context of exercise and sport. This study aims to provide insight on whether the immediate outcomes (e.g., central and peripheral acute responses) may be intensified or attenuated when a HIIT protocol is performed using a FFP2/N95 face mask in active healthy adult women. In other words, it strives to provide new findings relative to the use of face masks as a potential performance enhancing tool. In the current study, the same training session was carried out on two occasions under different conditions (i.e., with FFP2/N95 and without FFP2/N95) in a cross-over experimental design. The following study variables were assessed before and after the HIIT in both sessions: Lactate, cortisol, alpha-amylase, selective attention, countermovement jump (CMJ), and power output. Additionally, central and peripheral Rates of Perceived Exertion (RPE) were assessed before and during the HIIT. This study makes novel contributions to prior research, showing that the use of FFP2/N95 face mask (vs. no mask) yielded higher alpha-amylase, selective attention, and peripheral RPE scores. No significant differences were found for lactate, cortisol, CMJ, and power output. Interestingly, central RPE scores were significantly lower under FFP2/N95 face mask (vs. no mask) condition. The main suggestion in light of these results is that researchers and practitioners should consider potential peripheral and central responses to training stimuli when using FFP2/N95 face masks.

Influence of Exogenous Factors Related to Nutritional and Hydration Strategies and Environmental Conditions on Fatigue in Endurance Sports: A Systematic Review with Meta-Analysis.

The aim of this systematic review with meta-analysis was to examine the influence of exogenous factors related to nutritional and hydration strategies and environmental conditions, as modulators of fatigue, including factors associated with performance fatigability and perceived fatigability, in endurance tests lasting 45 min to 3 h. A search was carried out using four databases: PubMed, Web of Science, SPORTDiscus, and EBSCO. A total of 5103 articles were screened, with 34 included in the meta-analysis. The review was registered with PROSPERO (CRD42022327203) and adhered to the PRISMA guidelines. The study quality was evaluated according to the PEDro score and assessed using Rosenthal's fail-safe N. Carbohydrate (CHO) intake increased the time to exhaustion (p < 0.001) and decreased the heart rate (HR) during the test (p = 0.018). Carbohydrate with protein intake (CHO + PROT) increased lactate during the test (p = 0.039). With respect to hydration, dehydrated individuals showed a higher rate of perceived exertion (RPE) (p = 0.016) and had a higher body mass loss (p = 0.018). In hot conditions, athletes showed significant increases in RPE (p < 0.001), HR (p < 0.001), and skin temperature (p = 0.002), and a decrease in the temperature gradient (p < 0.001) after the test. No differences were found when athletes were subjected to altitude or cold conditions. In conclusion, the results revealed that exogenous factors, such as nutritional and hydration strategies, as well as environmental conditions, affected fatigue in endurance sports, including factors associated with performance fatigability and perceived fatigability.

Polarization of Attitudes as a Function of Mortality Salience: A Meta-Cognitive Analysis.

BACKGROUND: The present study analyzes how attitudes can polarize after reminders of death in the context of persuasion, and proposes that a meta-cognitive process (i.e., self-validation) can serve as a compensatory coping mechanism to deal with mortality salience. METHOD: Participants were first asked to read either a strong or a weak resume of a job applicant. Next, they listed their initial thoughts about that applicant. Then, they were asked to think about of their own death (i.e., mortality salience condition) versus being asked to think about of being cold (i.e., control condition). Finally, participants reported the confidence in their thoughts, as well as their attitudes towards the applicant. RESULTS: Participants who were assigned to the mortality salience (vs. control) condition showed greater impact of their previously generated thoughts on their subsequent attitudes. Additionally, as hypothesized, this effect of attitude polarization was mediated by changes in thought confidence. CONCLUSIONS: Attitudes unrelated to mortality can be polarized by reminders of death and this effect can operate through a meta-cognitive process of thought validation. Implications for persuasion, self-validation, and beyond are discussed.

Meta-Analytic Use of Balanced Identity Theory to Validate the Implicit Association Test.

This meta-analysis evaluated theoretical predictions from balanced identity theory (BIT) and evaluated the validity of zero points of Implicit Association Test (IAT) and self-report measures used to test these predictions. Twenty-one researchers contributed individual subject data from 36 experiments (total N = 12,773) that used both explicit and implicit measures of the social-cognitive constructs. The meta-analysis confirmed predictions of BIT's balance-congruity principle and simultaneously validated interpretation of the IAT's zero point as indicating absence of preference between two attitude objects. Statistical power afforded by the sample size enabled the first confirmations of balance-congruity predictions with self-report measures. Beyond these empirical results, the meta-analysis introduced a within-study statistical test of the balance-congruity principle, finding that it had greater efficiency than the previous best method. The meta-analysis's full data set has been publicly archived to enable further studies of interrelations among attitudes, stereotypes, and identities.

[Attitude change toward body image: the role of elaboration on attitude strength]. / Cambio de actitudes hacia la imagen corporal: el efecto de la elaboración sobre la fuerza de las actitudes.

Attitude change toward body image: The role of elaboration on attitude strength. Attitudes toward body image have been shown to play a central role in the understanding and treating of eating disorders. In the present research, participants' attitudes toward their body image were changed through a persuasive procedure involving high mental elaboration (self-persuasion) or through a less engaging procedure involving less active participation (passive exposure). As expected, participants in these two groups showed more favourable attitudes toward their bodies than those in the control group. Despite that both treatments were equally efficient in changing attitudes, the strength associated with those attitudes was significantly different depending on the amount of thinking involved in the process of change. Specifically, attitudes were stronger in the high rather than low thinking group of treatment. This finding is important because the strength of the attitude may determine the long-term consequences of an intervention.

Development of an implicit overall well-being measure using the Implicit Association Test.

Usually, well-being has been measured by means of questionnaires or scales. Although most of these methods have a high level of reliability and validity, they present some limitations. In order to try to improve well-being assessment, in the present work, the authors propose a new complementary instrument: The Implicit Overall Well-Being Measure (IOWBM). The Implicit Association Test (IAT) was adapted to measure wellbeing by assessing associations of the self with well-being-related words. In the first study, the IOWBM showed good internal consistency and adequate temporal reliability. In the second study, it presented weak correlations with explicit well-being measures. The third study examined the validity of the measure, analyzing the effect of traumatic memories on implicit well-being. The results showed that people who remember a traumatic event presented low levels of implicit well-being compared with people in the control condition.

Need for cognition can magnify or attenuate priming effects in social judgment.

This article hypothesizes that the individual-difference variable, need for cognition (NFC), can have opposite implications for priming effects, depending on prime blatancy. Subtle primes are argued to be more effective for high- versus low-NFC individuals. This is because for high-NFC individuals, (a) constructs are generally easier to activate, (b) their higher amount of thought offers more opportunity for an activated construct to bias judgment, and (c) their thoughtfully formed judgments are more likely to affect behavior. However, because high-NFC individuals are adept at identifying and correcting for bias, with blatant primes the activated construct should be less likely to exert its default influence. Furthermore, with blatant primes, low-NFC individuals may achieve sufficient activation for primes to affect judgment. Across three studies, it is shown that as NFC increases, the magnitude of priming effects increases with a subtle prime but decreases with a blatant prime.

[Need to evaluate: an assessment proposal in Spanish]. / Necesidad de evaluación: propuesta para su medición en castellano.

Everybody evaluates objects in terms of good and bad. Besides this general tendency, some individuals are more motivated than others to make evaluative judgments. Individual differences in this need to evaluate can be reliably assessed with the Need to Evaluate (NE) Scale development by Jarvis and Petty. The purpose of the present work was to adapt the NE test to Spanish, and to assess its psychometric properties of reliability and validity . The first study revealed that the Spanish version of the NE test had a good internal consistency. A second study confirmed that the test also showed good properties in terms of discriminant validity. The NE correlated moderately with Need for Cognition and Need for Closure, and but not with Social Desirability.

Where Did This Thought Come From? A Self-Validation Analysis of the Perceived Origin of Thoughts.

Three experiments examined whether perceiving thoughts as coming from internal versus external origins are more impactful on attitudes. Participants generated either positive or negative thoughts about different attitude objects, including different diets, and plastic surgery. Then, participants were induced to think that their thoughts came from the self or from an external source. In Experiment 1, participants induced to believe their thoughts originated from the self versus an external source relied on them more to form their attitudes. Experiment 2 demonstrated that when the external origin was associated with properties of validity, people relied on their thoughts more than when thoughts were perceived to come from an internal origin associated with low validity. Experiment 3 showed that the impact of thought origin on evaluations was mediated by greater liking for one's thoughts when they originated in the self.

[Depression and the complete state model of health]. / La aplicación del modelo del estado completo de salud al estudio de la depresión.

Health is a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity. In order to specify the contents of this positive state, the Complete State Model of Health (CSMH) considers mental health as a series of symptoms of hedonia and positive functioning, operationalized by measures of subjective, psychological, and social well-being. This model has empirically confirmed two new axioms: (a) rather than forming a single bipolar dimension, health and illness are correlated unipolar dimensions, and (b) the presence of mental health implies positive personal and social functioning. In the present article, we have taken the CSMH as the theoretical framework for the study of depression. Confirmatory factor analyses did not support the first axiom. In fact, the model that posits that measures of mental illness and health form a single bipolar dimension provided the best fit to the data.
