Routine cognitive errors: A trait-like predictor of individual differences in anxiety and distress

Five studies (N=361) sought to model a class of errors—namely, those in routine tasks—that several literatures have suggested may predispose individuals to higher levels of emotional distress. Individual differences in error frequency were assessed in choice reaction-time tasks of a routine cognitive type. In Study 1, it was found that tendencies toward error in such tasks exhibit trait-like stability over time. In Study 3, it was found that tendencies toward error exhibit trait-like consistency across different tasks. Higher error frequency, in turn, predicted higher levels of negative affect, general distress symptoms, displayed levels of negative emotion during an interview, and momentary experiences of negative emotion in daily life (Studies 2–5). In all cases, such predictive relations remained significant with individual differences in neuroticism controlled. The results thus converge on the idea that error frequency in simple cognitive tasks is a significant and consequential predictor of emotional distress in everyday life. The results are novel, but discussed within the context of the wider literatures that informed them.     

Examination of relationships among trait-like individual differences, state-like individual differences, and learning performance

Several authors (e.g., J.T. Austin & H.J. Klein, 1996; R. Kanfer, 1990b, 1992) have urged researchers to examine comprehensive models of distal individual differences as predictors of proximal motivational processes and performance. Two field studies in an academic setting tested a model of relationships among trait-like individual differences (cognitive ability, general self-efficacy, and goal orientation), state-like individual differences (state anxiety, task-specific self-efficacy, and goals), and learning performance. Most hypothesized relationships among these constructs received support when tested on 2 samples, when examining different performance episodes, and when using different goal orientation and state-anxiety measures. In general, state-like individual differences were found to mediate the relationships between trait-like individual differences and learning performance. Implications of these results are discussed and suggestions for future research are provided.     

Process differences and individual differences in some cognitive tasks

This study is based on three distinct elementary cognitive tasks (ECTs) using chronometric techniques: (a) the S. Sternberg memory scan task, (b) a visual scan task which is perfectly analogous to the memory scan, except that the target digit is presented first and the subject must then scan a set of digits and indicate the presence or absence of the target digit in the set, and (c) the Hick paradigm, which involves responding to a visual stimulus (a light going “on”) when the stimulus is one among sets of either 1, 2, 4, or 8 equally probable alternatives. Certain parameters of all three tasks, such as intercept and slope of RT as a function of set size, from which different cognitive processes are inferred, are compared experimentally and correlationally. Subjects were 48 university students, tested and retested on the three tasks in a counterbalanced design on two separate days to obtain the retest reliabilities needed to correct all correlations for attenuation. Subjects were also given Raven's Advanced Progressive Matrices as a measure of psychometric g. Parameters of the ECTs are significantly and, in some cases, quite substantially correlated with g. Virtually all of this correlation is due to the general factor of the various ECTs, rather than to specific processing components (independent of the general factor). The results also indicate that different ECT paradigms (e.g., visual search and memory search tasks) may yield markedly different values in terms of the group means of analogous parameters, indicating different processes, and yet not show independence of the parameters in terms of individual differences; that is, measurements of the different parameters in individuals are perfectly correlated (i.e., disattenuated correlations do not differ significantly from r = 1). This is found for the intercept parameter of visual and memory search. The reverse condition is also found for the other parameters (e.g., slope); that is, their mean values are nearly identical, suggesting the same processes, yet disattenuated correlations between individual differences are relatively low, or even negative, indicating different processes. Although the general factor clearly predominates, it does not completely overwhelm individual differences in various component processes that are distinct from the general factor.     

Impulsivity and anxiety differences in cognitive inhibition

An identity negative priming task was employed to investigate cognitive inhibition in 245 undergraduates. The task presented consecutively a prime and a probe display that contained a target and a distractor. Negative priming is observed when subjects must respond to a target in the probe display that had been a distractor in the prime display. This task also served to study the Eriksen interference effect by comparing a condition in which the target and the distractor had the same identity with a condition in which they had different identities. Subjects completed the Sensitivity to Punishment and Sensitivity to Reward Questionnaire designed to measure Gray's anxiety and impulsivity dimensions. Results showed that impulsives had a lower cognitive inhibition than non-impulsives, whereas impulsive women also showed a greater Eriksen interference effect than non-impulsive women. Furthermore, no differences in task performance were found between anxious and non-anxious groups. Our discussion considers the importance of studying cognitive functioning in personality research.     

Trait empathy as a predictor of individual differences in perceived loneliness

Loneliness has been shown to be inversely correlated with empathy in younger adults. The present study extends previous research by investigating the association between empathy and loneliness across the adult lifespan and examining the role of relevant demographic and personality factors. 110 community-dwelling adults (18 to 81 years old) completed the UCLA Loneliness Scale and the Empathy Quotient. Empathy scores were inversely associated with rated loneliness and predicted 8.7% of variance in loneliness scores after accounting for sex, age, relationship status, education, and neuroticism. The Social Skills factor of the Empathy Quotient was the strongest predictor of the association between perceived empathy and loneliness. Previous research is extended by the finding that rated loneliness was inversely associated with empathy scores across the adult lifespan. Underlying this relationship may be negative perceptions of personal social proclivity as a function of difficulty in understanding the mental states of others and high trait neuroticism.     

Neighborhood crime as a predictor of individual differences in emotional processing and regulation

Emerging research suggests that early exposure to environmental adversity has important implications for the development of brain regions associated with emotion regulation, yet little is known about how such adversity translates into observable differences in children's emotion‐related behavior. The present study examines the relationship between geocoded neighborhood crime and urban pre‐adolescents' emotional attention, appraisal, and response. Results indicate that living in a high‐crime neighborhood is associated with greater selective attention toward negatively valenced emotional stimuli on a dot probe task, less biased appraisal of fear on a facial identification task, and lower rates of teacher‐reported internalizing behaviors in the classroom. These findings suggest that children facing particularly high levels of environmental threat may develop different regulatory processes (e.g. greater use of emotional suppression) than their peers from low‐crime neighborhoods in order to manage the unique stressors and social demands of their communities.     

Appreciation: individual differences in finding value and meaning as a unique predictor of subjective well-being

Adler (2002; Adler & Fagley, 2001) argued that being appreciative facilitates and enhances feelings of well-being and life satisfaction, as well as feelings of connection to what we have, to what we experience, and to life itself. In addition, expressing appreciation to others is believed to build social bonds. Although appreciation is viewed as a disposition, it is also viewed as something people can learn over time, making it an especially valuable construct to measure. Appreciating something (e.g. an event, a person, a behavior, an object) involves noticing and acknowledging its value and meaning and feeling a positive emotional connection to it. We defined eight aspects of appreciation and developed scales to measure them: a focus on what one has ("Have" Focus), Awe, Ritual, Present Moment, Self/Social Comparison, Gratitude, Loss/Adversity, Interpersonal. Scores on the subscales may be totaled to yield a score representing one's overall degree of appreciation (or level of appreciativeness) (coefficient alpha=.94). We also developed an 18-item short form (coefficient alpha=.91) that correlates .95 with scores on the long form. The scales correlated in predicted ways with measures of life satisfaction, positive affect, and negative affect. More importantly, appreciation was significantly related to life satisfaction and positive affect, even after the effects of optimism, spirituality, and emotional self-awareness had been statistically controlled.     

Decision framing: moderating effects of individual differences and cognitive processing

Two studies examined the effect of an individual difference variable, need for cognition (NC), and processing of the options on the occurrence of risky choice framing effects. In Study 1 (N=206), frame interacted with NC and math skill such that no framing effect was observed among those high in both NC and math skill. No effect was found for the processing manipulation of requesting a reason for one's choices. Study 2 (N=257) enhanced the processing of the problems by asking participants to write out the options as they would describe them to a friend. Results showed that frame interacted with NC and depth of processing such that no framing effect was observed among those high in NC who were in the deep processing condition. These findings suggest that NC and depth of processing need to be considered in concert in order to understand their moderating effects on framing. Copyright © 2004 John Wiley & Sons, Ltd.     

The role of individual differences in cognitive training and transfer

Working memory (WM) training has recently become a topic of intense interest and controversy. Although several recent studies have reported near- and far-transfer effects as a result of training WM-related skills, others have failed to show far transfer, suggesting that generalization effects are elusive. Also, many of the earlier intervention attempts have been criticized on methodological grounds. The present study resolves some of the methodological limitations of previous studies and also considers individual differences as potential explanations for the differing transfer effects across studies. We recruited intrinsically motivated participants and assessed their need for cognition (NFC; Cacioppo & Petty Journal of Personality and Social Psychology 42:116–131, 1982) and their implicit theories of intelligence (Dweck, 1999) prior to training. We assessed the efficacy of two WM interventions by comparing participants’ improvements on a battery of fluid intelligence tests against those of an active control group. We observed that transfer to a composite measure of fluid reasoning resulted from both WM interventions. In addition, we uncovered factors that contributed to training success, including motivation, need for cognition, preexisting ability, and implicit theories about intelligence.     

Motivation towards closure and cognitive processes: An individual differences approach

Two studies (N = 212) examined the relationships between elementary cognitive processes and individual differences in the need for cognitive closure. The results indicated that the need for closure is linked with certain cognitive deficits, specifically a restricted pool of cognitive resources allocated to a current activity. It was also found that these cognitive limitations tend to be compensated for by a particularly efficient process of information-selection from the environment. However, the selection process is costly, thus in a situation of drainage of cognitive resources its effectiveness also drops and the selection advantage of high (vs. low) need for closure individuals is eliminated.

Emotional intelligence as a unique predictor of individual differences in humour styles and humour appreciation

A small amount of research to-date has examined the association between emotional intelligence (EI) and humour styles, however, none of this research has controlled for the effects of personality and socially desirable responding. Furthermore, none of the research has examined the possible associations with humour appreciation, as distinct from humour styles. Thus, a novel audio-visual humour appreciation measure (AVHAM) was developed based on responses to ostensibly humorous video clips. The AVHAM was found to be associated with factorial validity, as three, positively correlated factors emerged (aggressive, children, and animals). Additionally, convergent validity was observed for the AVHAM, as theoretically consistent and moderately sized correlations were observed between the AVHAM and the Humour Styles Questionnaire (HSQ). Finally, incremental predictive validity was found to be associated with self-reported EI and humour styles, but not humour appreciation. The results are discussed in light of the distinction between humour styles and humour appreciation, as well as the unique role of EI in understanding individual differences in humour.     

Sensitive maintenance: a cognitive process underlying individual differences in memory for threatening information

Dispositional styles of coping with threat influence memory for threatening information. In particular, sensitizers excel over repressors in their memory for threatening information after long retention intervals, but not after short ones. We therefore suggested that sensitizers, but not repressors, employ active maintenance processes during the retention interval to selectively retain threatening material. Sensitive maintenance was studied in 2 experiments in which participants were briefly exposed to threatening and nonthreatening pictures (Experiment 1, N = 128) or words (Experiment 2, N = 145). Following, we administered unannounced recognition tests before and after an intervening task that generated either high or low cognitive load, assuming that high cognitive load would impede sensitizers' memory maintenance of threatening material. Supporting our hypotheses, the same pattern of results was obtained in both experiments: Under low cognitive load, sensitizers forgot less threat material than repressors did; no such differences were observed under high cognitive load.     

A cognitive analysis of number-series problems: Sources of individual differences in performance

Two experiments were conducted to identify the roles of three hypothesized procedures in the solution of simple number-series problems and to determine whether individual differences in these solution procedures are related to performance on a number-series subtest from a standardized test of intelligence. The three procedures are recognition of memorized series, calculation, and checking. Subjects verified whether number sequences formed rule-based series. True series included both memorized counting series (e.g., “5 10 1520”) and unfamiliar noncounting series (e.g., “14 710”). False series could not be described by simple rules. The results of Experiment 1 indicated that (1) counting series were verified more quickly than were noncounting series, and (2) partial counting information in false series facilitated rejection. In Experiment 2, reliable differences in recognition of memorized sequences and calculational efficiency were found between individuals who scored well on a standardized test of number-series completion and those who scored poorly. The results provide a basis for understanding how individual differences in knowledge influence performance on problems often used to assess inductive reasoning skill.

Self-guides, autobiographical memory, and anxiety and dysphoria: toward a cognitive model of vulnerability to emotional distress.

Several aspects of a cognitive model of vulnerability to emotional disorders based on self-discrepancy theory were tested. Anxious, dysphoric, anxious/dysphoric, and control subjects participated in 3 studies over a 4-month period: screening, assessment of self-guides and self-discrepancies, and an autobiographical memory task in which different types of retrieval cues (including self-guides) were presented and subjects reported childhood memories as they came to mind. Actual:ideal discrepancy was associated with persistent dysphoria, whereas actual:ought discrepancy was associated with persistent anxiety. Self-guide cues resulted in more efficient retrieval and greater unintended negative emotional content than comparable cue types. The groups were differentiated only by negative affect content in response to self-guide cues.
