Deleterious effects of alcohol intoxication: diminished cognitive control and its behavioral consequences

The authors tested the hypothesis that impaired behavioral performance during intoxication results partly from alcohol's deleterious effects on cognitive control. The impact of alcohol on perseverative behavior was examined with an n-back working memory task that included manipulations of task complexity and prepotency of inclinations to respond or withhold responding. Thirty-two social drinkers (16 men) participated in either an alcohol (.075g/100ml) or a no-alcohol condition. Alcohol increased perseveration of prepotent, task-inappropriate response patterns only under cognitively demanding (heavy memory load) conditions. This effect was evident for both commission errors (response persistence despite contingencies altered to require restraint) and omission errors (failure to respond when contingencies were revised to encourage action). Findings suggested that alcohol-induced perseveration arises from impairments in cognitive control.     

Training the brain: fact and fad in cognitive and behavioral remediation

Putatively safe and effective for improving cognitive performance in both health and disease, products purported to train the brain appeal to consumers and healthcare practitioners. In an increasingly health-centered society, these applications constitute a burgeoning commercial market. Sparse evidence coupled with lack of scientific rigor, however, leaves claims concerning the impact and duration of such brain training largely unsubstantiated. On the other hand, at least some scientific findings seem to support the effectiveness and sustainability of training for higher brain functions such as attention and working memory. In the present paper we provide a tectonic integration and synthesis of cognitive training approaches. Specifically, we sketch the relative merits and shortcomings of these programs, which often appeal to parents who must choose between side-effect-laden medication and other less conventional options. Here we examine how neuroplasticity allows the healthy as well the impaired to benefit from cognitive training programs. We evaluate the evidence and consider whether brain training can be a stand-alone treatment or an adjunct to pharmacotherapy, outline promising future prospects, and highlight what training outcomes are plausible in line with available data. Future research would determine whether the field of brain training realizes its potential to revolutionize education and rehabilitation or withers away engulfed in controversy.     

Ethnophaulisms and exclusion: the behavioral consequences of cognitive representation of ethnic immigrant groups

Ethnophaulisms are the words used as slurs to refer to ethnic immigrant outgroups. This article explores the effects of these cognitive representations of ethnic immigrant groups on exclusion behavior directed toward these immigrant groups. Using archival data spanning a 150-year period of American history, the results of these analyses provide a sobering picture of the effects of the cognitive representation of immigrants: a century and a half of thinking about ethnic immigrant groups in a simplistic and negative manner and a corresponding tendency to exclude those immigrant groups from the receiving society. The implications of these results for theoretical approaches to intergroup relations are considered.     

Socially triggered negative affect impairs performance in simple cognitive tasks

The aim of this research was to investigate the influence of a social-evaluative context on simple cognitive tasks. While another person present in the room evaluated photographs of beautiful women or landscapes by beauty/attractiveness, female participants had to perform a combination of digit-categorization and spatial-compatibility task. There, before every trial, one of the women or landscape pictures was presented. Results showed selective performance impairments: the numerical distance effects increased on trials that followed women pictures but only, if another person concurrently evaluated these women pictures. In a second experiment, using the affective priming paradigm, the authors show that female pictures have a more negative connotation when they are concurrently evaluated by another person (social-evaluative context) than when they are not evaluated (neutral context). Together, these results suggest that the social-evaluative context triggers mild negative affective reactions to women pictures which then impair performance in an unrelated task.     

Blirtatiousness: cognitive, behavioral, and physiological consequences of rapid responding.

The Brief Loquaciousness and Interpersonal Responsiveness Test (BLIRT) measures the extent to which people respond to others quickly and effusively. The BLIRT displays desirable psychometric properties and distinguishes people who should theoretically score high (e.g., car salespersons) from those who should score low (e.g., librarians). Scores on the scale predict (a) the amount and rapidity of people's verbal responses in an unstructured interaction, (b) how likable and competent people's classmates perceive them to be early in the semester, (c) how quickly people respond to an obnoxious cell-phone user and how physiologically aroused they become, and (d) how quickly and emphatically people respond to a series of personal insults as well as their degree of physiological arousal. Converging evidence indicates that blirtatiousness is unique in its ability to amplify people's qualities, making these qualities more readily observable to perceivers.     

Protective behavioral strategies and the relationship between depressive symptoms and alcohol-related negative consequences among college students

Approximately 40% of college students reported engaging in heavy episodic or "binge" drinking in the 2 weeks prior to being surveyed. Research indicates that college students suffering from depression are more likely to report experiencing negative consequences related to their drinking than other students are. The reasons for this relationship have not been well-studied. Hence, the purpose of this study was to determine whether use of protective behavioral strategies (PBS), defined as cognitive-behavioral strategies an individual can use when drinking alcohol that limit both consumption and alcohol-related problems, mediated the relationship between depressive symptoms and alcohol-related negative consequences among college students. Data were obtained from 686 participants from a large, public university who were referred to an alcohol intervention as a result of violating on-campus alcohol policies. Results from structural equation modeling analyses indicated that use of PBS partially mediated the relationship between depressive symptoms and alcohol-related negative consequences. Implications for clinicians treating college students who report experiencing depressive symptoms or consuming alcohol are discussed.

Effectiveness of cognitive behavioral therapy on the signs,symptoms and clinical consequences of premature ejaculation

The purpose of this research was to assess the effectiveness of cognitive behavioral therapy (CBT) on the signs, symptoms, and clinical‐sexual consequences of premature ejaculation, including sexual esteem, sexual anxiety, sexual depression, sexual fear, and sexual satisfaction of patients and their wives. Fifteen patients with premature ejaculation were selected and received cognitive behavioral therapy of eight to 12 sessions. Finally, the data collected from 12 patients were analyzed using paired t‐tests. The results of the analysis showed that all of the variables changed after the treatment. All of the changes were statistically significant with a tendency towards improvement. CBT can be a more popular and effective treatment provided to patients suffering from premature ejaculation.     

A naturalistic study of fat talk and its behavioral and affective consequences

Fat talk is a style of verbal expression among young women involving negative self-statements, complaints about physical appearance, and weight management. This research used ecological momentary assessment to examine the impact of naturalistic fat talk experiences on body dissatisfaction, body checking, negative affect, and disordered eating behaviors. We examined trait self-objectification as a moderator. Sixty-five female college students completed a baseline questionnaire and responded to questions when randomly prompted by palm pilot devices for five days. Results indicated fat talk is common and associated with greater body dissatisfaction, body checking, negative affect, and disordered eating behaviors. Fat talk participation was associated with greater body checking than overhearing fat talk. Greater trait self-objectification was associated with greater body dissatisfaction and body checking following fat talk. These results suggest that fat talk negatively impacts the cognitions, affect, and behavior of young women and has increased negative effects for women higher in self-objectification.     

Self-ratings of positive and negative affect and retrieval of positive and negative affect memories

Abstract

Based on analysis of self-ratings of mood, positive affect (PA) and negative affect (NA) have been proposed as basic, orthogonal mood dimensions (Watson & Tellegen, 1985). The present study asked subjects (N = 61) to not only provide self-ratings of PA and NA terms but also to retrieve personal memories associated with those terms. Self-rated PA was associated with latency to retrieve PA- but not NA-related memories; self-rated NA was associated with latency to retrieve NA- but not PA-related memories. Self-ratings of PA and NA were not significantly correlated, nor were retrieval latencies for PA and NA memories. Individual item correlations also revealed a strong direct relationship between self-ratings and retrieval latency. The dissociations involving a non-self report measure strengthen the distinction between PA and NA, and the individual item correlations are interpreted as showing that self-ratings of affect are based upon the ease of retrieval of personal memories.

Neurodevelopmental consequences of pediatric cancer and its treatment: applying an early adversity framework to understanding cognitive,behavioral, and emotional outcomes

Today, children are surviving pediatric cancer at unprecedented rates, making it one of modern medicine’s true success stories. However, we are increasingly becoming aware of several deleterious effects of cancer and the subsequent “cure” that extend beyond physical sequelae. Indeed, survivors of childhood cancer commonly report cognitive, emotional, and psychological difficulties, including attentional difficulties, anxiety, and posttraumatic stress symptoms (PTSS). Cognitive late- and long-term effects have been largely attributed to neurotoxic effects of cancer treatments (e.g., chemotherapy, cranial irradiation, surgery) on brain development. The role of childhood adversity in pediatric cancer – namely, the presence of a life-threatening disease and endurance of invasive medical procedures – has been largely ignored in the existing neuroscientific literature, despite compelling research by our group and others showing that exposure to more commonly studied adverse childhood experiences (i.e., domestic and community violence, physical, sexual, and emotional abuse) strongly imprints on neural development. While these adverse childhood experiences are different in many ways from the experience of childhood cancer (e.g., context, nature, source), they do share a common element of exposure to threat (i.e., threat to life or physical integrity). Therefore, we argue that the double hit of early threat and cancer treatments likely alters neural development, and ultimately, cognitive, behavioral, and emotional outcomes. In this paper, we (1) review the existing neuroimaging research on child, adolescent, and adult survivors of childhood cancer, (2) summarize gaps in our current understanding, (3) propose a novel neurobiological framework that characterizes childhood cancer as a type of childhood adversity, particularly a form of early threat, focusing on development of the hippocampus and the salience and emotion network (SEN), and (4) outline future directions for research.     

Error-related psychophysiology and negative affect

The error-related negativity (ERN/Ne) and error positivity (Pe) have been associated with error detection and response monitoring. More recently, heart rate (HR) and skin conductance (SC) have also been shown to be sensitive to the internal detection of errors. An enhanced ERN has consistently been observed in anxious subjects and there is some suggestion that the ERN is related to general negative affective experience (NA). The ERN has been source localized to the anterior cingulate cortex-a structure implicated in the regulation of affective, response selection, and autonomic resources. Thus, the findings that autonomic measures and affective distress are related to response monitoring are consistent with anterior cingulate cortex function. In the present experiment, we sought to evaluate more comprehensively the relationship between self-reported negative affect and error-related physiology in a between-groups design. Results indicate that high NA was associated with significantly greater ERN and error-related SCR, and smaller Pe. These results are discussed in terms of anterior cingulate cortex function, psychopathology, and response monitoring.     

Distinguishing the cognitive and behavioral consequences of attitude importance and certainty: A new approach to testing the common-factor hypothesis

Some published factor analyses have suggested that attitude importance and certainty are distinct psychological constructs, but other factor analytic investigations have suggested they are largely redundant reflections of a more general underlying construct. This latter sort of finding has led investigators to average measures of importance and certainty together into a composite index and then explore its cognitive and behavioral consequences. In this paper, we report three studies gauging the underlying structure of these strength-related attitude attributes by assessing whether they in fact relate in the same ways to information processing and action tendencies. We found that importance and certainty both independently predicted the likelihood that a person attempted to persuade others to adopt his or her attitude. Importance (but not certainty) was associated with the tendency to seek out information that would enable people to use their attitudes in a subsequent judgment and only importance predicted whether or not they turned out to vote in an election to express their attitudes. Certainty (but not importance) was related to the tendency to find more than one political candidate acceptable. And importance and certainty interacted to predict the frequency with which people performed attitude-expressive behaviors. All this suggests that importance and certainty have distinct effects on thinking and behavior and supports the maintenance of conceptual and empirical distinctions between them in social psychological theory building.     

Cognitive adaptation and its consequences: a test of cognitive continuum theory

Cognitive Continuum Theory (CCT) is an adaptive theory of human judgement and posits a continuum of cognitive modes anchored by intuition and analysis. The theory specifies surface and depth task characteristics that are likely to induce cognitive modes at different points along the cognitive continuum. The current study manipulated both the surface (information representation) and depth (task structure) characteristics of a multiple‐cue integration threat assessment task. The surface manipulation influenced cognitive mode in the predicted direction with an iconic information display inducing a more intuitive mode than a numeric information display. The depth manipulation influenced cognitive mode in a pattern not predicted by CCT. Results indicate this difference was due to a combination of task complexity and participant satisfacing. As predicted, analysis produced a more leptokurtic error distribution than intuition. Task achievement was a function of the extent to which participants demonstrated an analytic cognitive mode index, and not a function of correspondence, as predicted. This difference was likely due to the quantitative nature of the task manipulations. Copyright © 2000 John Wiley & Sons, Ltd.     

The independence of positive and negative affect depends on the affect measure

This study examined the degree of independence between Positive Affect (PA) and Negative Affect (NA) within a given situation. The affective state was measured before and after an experimentally induced success or failure experience in an anagram task. Two types of affect measures were used to assess PA and NA: the Positive and Negative Affect Schedule (PANAS) and a Pleasantness-Unpleasantness scale. Consistent with our hypotheses, results show that PA and NA are independent when measured with the PANAS but are correlated when assessed with the other scale. These PA-NA correlations differed significantly from each other before and after emotion induction, respectively. Additional analyses indicate that both PA scales are differentially sensitive to the mood induction procedure. The findings are discussed with respect to circumplex models of emotion.
