RESUMO

Accelerated long-term forgetting (ALF) has been reported in healthy older individuals, and is a possible early marker for risk of developing Alzheimer's disease (AD). The Verbal Associative Learning and Memory Test (VALMT) addresses methodological weaknesses in existing clinical tests and has detected ALF in epilepsy within an hour. We used VALMT to investigate learning and forgetting in healthy Older participants. Older (60-69 years) and Younger (19-31 years) participants were compared. Using VALMT, unrelated word pairs were learnt to criterion, then cued-recall tested at delays of 5, 30, and 55 min. Unique pairs were tested at each delay. Subjective memory complaints data was gathered, and the Wechsler Memory Scale Logical Memory test (WMS-LM; a standard clinical measure) was administered. VALMT identified a significant difference in delayed recall between Younger and Older groups by 55 min (d = 1.32). While "fast-learning" Older participants scored similarly to Younger participants, "slow-learning" Older participants were impaired at all delays. Forgetting rates suggested degradation of memory starts during early synaptic consolidation rather than later system-level consolidation. Increased subjective memory complaints were associated with reduced VALMT scores. By contrast, WMS-LM failed to identify significant differences between any groups, and did not correlate with memory complaints. We conclude that VALMT may be better able than WMS-LM to identify subtle impairments in healthy older adults within a single clinical visit, and VALMT results better reflect subjective experience. Older slow-learners forget faster and report more subjective memory complaints, which may indicate a group at risk of developing AD.

RESUMO

Implicit learning (IL) deals with the non-conscious acquisition of structural regularities from the environment. IL is often deemed essential for acquiring regularities followed by social stimuli (e.g., other persons' behavior), hence is hypothesized to play a role in typical social functioning. However, our understanding of how this process might operate in social contexts is limited for two main reasons. First, while IL is highly sensitive to the characteristics of the surface stimuli upon which it operates, most IL studies have used surface stimuli with limited social validity (e.g., letters, symbols, etc.). Second, while the social environment is dynamic (i.e., our behaviors and reactions influence those of our social partners and vice-versa), the bulk of IL research employed noninteractive paradigms. Using a novel task, we examine whether IL is involved in the acquisition of regularities from a dynamic interaction with a realistic real-life-like agent. Participants (N = 115) interacted with a cinematic avatar that displayed different facial expressions. Their task was to regulate the avatar's expression to a specified level. Unbeknownst to them, an equation mediated the relationship between their responses and the avatar's expressions. Learning occurred in the task, as participants gradually increased their ability to bring the avatar in the target state. Subjective measures of awareness revealed that participants acquired both implicit and explicit knowledge from the task. This is the first study to show that IL operates in interactive situations upon socially relevant surface stimuli, facilitating future investigations of the role that IL plays in (a)typical social functioning.

RESUMO

Anxiety disorders (ADs) are among the most common psychiatric disorders and they may appear as early on as in childhood. The current study addressed the combination of two treatments approaches for ADs: Dance/movement therapy (DMT) and cognitive behavioral therapy (CBT), focusing on factors that explain the therapists' attitudes towards actually combining the two therapies. The study utilized a quantitative design, with a perceptions survey administered via an online questionnaire. Ninety-nine therapists participated in the study (DMT-only n = 35, CBT-only n = 42, and DMT + CBT, n = 22). Following preliminary analysis (comparison between the groups, correlations and factor analysis), the structural equation model (SEM, confirmatory factor analysis) revealed a good fit between the theoretical model and the empirical data. First, it was found that the reported actual use of the combined approaches (DMT + CBT) in treatment of children with ADs, was significantly explained by therapists who had experience practicing DMT but not CBT perceiving this combination as efficient. Second, the therapists' use of the combined therapy (DMT + CBT) approaches was not related to their sense of efficacy as therapists of children with ADs. The model represents concordance between the components of the therapists' attitudes: Affective-belief that it is efficient, cognitive-perception of it as effective, and behavioral-their actual use.

RESUMO

Evaluative conditioning (EC) refers to the acquisition of emotional valence by an initially neutral stimulus (conditioned stimulus [CS]) after being paired with an emotional stimulus (unconditioned stimulus [US]). An important issue regards whether, when participants are unaware of the CS-US contingency, the affective valence can generalize to new stimuli that share similarities with the CS. Previous studies have shown that generalization of EC effects appears only when participants are aware of the contingencies, but we suggest that this is because (a) the contingencies typically used in these studies are salient and easy to detect consciously, and (b) the performance-based measures of awareness (so-called "objective measures"), typically used in these studies, tend to overestimate the amount of available conscious knowledge. We report a preregistered study in which participants (N = 217) were exposed to letter strings generated from two complex artificial grammars that are difficult to decipher consciously. Stimuli from one grammar were paired with positive USs, whereas those from the other grammar were paired with negative USs. Subsequently, participants evaluated new, previously unseen, stimuli from the positively conditioned grammar more positively than new stimuli from the negatively conditioned grammar. Importantly, this effect appeared even when trial-by-trial subjective measures indicated lack of relevant conscious knowledge. We provide evidence for the generalization of EC effects even without subjective awareness of the structures that enable those generalizations.

RESUMO

The present three-wave longitudinal study provides empirical evidence for the mechanisms of the bright and dark sides of identity development in the academic context. First, we investigated the patterns of stability and change in educational identity and academic achievement among adolescents. Second, we examined the reciprocal associations between identity processes (i.e., commitment, in-depth exploration, and reconsideration of commitment) and academic achievement. The main results of the study highlighted that academic achievement predicts the manner in which adolescents deal with their identity issues in the academic context. Thus, high academic achievement leads to high levels of commitment (identity synthesis), while low academic achievement leads to high levels of reconsideration of commitment (identity confusion). This unidirectional pattern of effects applied equally to adolescent boys and girls, early-to-middle and middle-to-late adolescents, and to adolescents attending theoretical and vocational schools. Practical implications are discussed.

RESUMO

Early life stress (ELS) has been recently associated with blunted cortisol reactivity and emotion dysregulation, but no study until now examined whether these characteristics are related. The main goal of this study was to examine the potential mediator role of emotion dysregulation in the relation between ELS and cortisol reactivity to social threat. Only women who were free of psychiatric and endocrine disorders, had regular menstrual cycle and did not use oral contraceptives were selected for this study (N=62). After filling in ELS and multidimensional emotion dysregulation measures, participants underwent the Trier Social Stress Test during which cortisol and autonomic responses were assessed. Most participants (85.5%) reported one or more major stressful events (i.e., physical abuse, sexual abuse, major parental conflicts, death of a family or close friend, severe illness) experienced before age 17. ELS was negatively associated with cortisol reactivity and positively associated with skin conductance level (SCL) reactivity, but it did not influence heart rate and respiratory sinus arrhythmia. In addition, ELS was positively related to emotional non-acceptance (i.e., a tendency to develop secondary emotional responses to one's negative emotions), and the latter was negatively related to cortisol responses and positively related to SCL responses. Bootstrapping analyses indicated that emotional non-acceptance was a significant mediator in the relationships between ELS and both cortisol and SCL responses. Emotional non-acceptance is thus one of the psychological mechanisms underlying blunted cortisol and increased sympathetic reactivity in young healthy volunteers with a history of ELS.

RESUMO

Emotional arousal can both enhance and impair memory. Considering that both emotional memory and trait anxiety (TA) have been associated with adrenergic activity, the authors investigated whether there is an association between 2 opposite emotional memory biases and the TA. The authors used a procedure recently put forward by B. A. Strange, R. Hurlemann, and R. J. Dolan (2003) to elicit an emotion-induced retrograde amnesia (ERA) coupled to an emotional memory enhancement (EME). The authors contrasted the association between these emotional memory biases and the TA in several conditions involving different levels of encoding and types of recall. The results presented here indicated a significant interaction of the TA with EME and ERA and the dependency of these biases on the consciously controlled use of memory.

RESUMO

Cognitive psychology attempts to understand the nature of the human mind by using the information-processing approach. In this article, the fundamentals of the cognitive approach will be presented. It will be argued that the human mind can be described at three levels-computational, algorithmic-representational, and implementational-and that the cognitive approach has both important theoretical and practical/clinical implications. Finally, it will be suggested that the study of cognitive psychology can provide a foundation for other fields of social science, including the field of clinical psychology.
