When the brain decides: a familiarity-based approach to the recognition heuristic as evidenced by event-related brain potentials

Humans can make fast and highly efficient decisions by using simple heuristics that are assumed to exploit basic cognitive functions. In the study reported here, we used event-related potentials (ERPs) to disclose the psychological mechanisms underlying one of the most frugal decision rules, namely, the recognition heuristic. According to this heuristic, whenever two objects have to be ranked by a specific criterion and only one object is recognized, the recognized object is ranked higher than the unrecognized object. Using a standard recognition-heuristic paradigm, we predicted participants' decisions by analyzing an ERP correlate of familiarity-based recognition occurring 300 to 450 ms after stimulus onset. The measure remained a significant predictor even when later ERP correlates were taken into account. These findings are evidence for the thesis that simple heuristics exploit basic cognitive processes. Specifically, the findings show that familiarity--that is, recognition in the absence of recollection--contributes to decisions made on the basis of such heuristics.     

Does age make a difference? Predicting physical activity of South Koreans

Social cognition models of health behavior are commonly understood as being universal, which implies that they are applicable to groups varying in age or cultural background, for example. Cultural uniqueness and characteristics of life-span development, however, necessitate the study of differential effects. Accordingly, the health action process approach (HAPA) was examined in younger and middle-aged/older adults from South Korea (N = 697) who participated in a longitudinal health screening study with a 6-month time lag. The HAPA model had a good fit within the middle-aged/older adult sample. Physical activity was predicted by planning, coping self-efficacy, and intention, which were, in turn, predicted by action self-efficacy, outcome expectancies, and risk perceptions. Conversely, the results indicated a poor model fit in the younger adult sample. The results suggest a different motivation for the involvement in physical activity as a function of age.     

Mule cognition: a case of hybrid vigour?

This study compares the behaviour of the mule (Equus asinus × Equus caballus) with that of its parent species to assess the effects of hybridization on cognition. Six mules, six ponies (E. caballus) and six donkeys (E. asinus) were given a two choice visual discrimination learning task. Each session consisted of 12 trials and pass level was reached when subjects chose the correct stimulus for at least 9 out of the 12 trials in three consecutive sessions. A record was made of how many pairs each subject learnt over 25 sessions. The mules’ performance was significantly better than that of either of the parent species (Kruskal-Wallis: H_x = 8.11, P = 0.017). They were also the only group to learn enough pairs to be able to show a successive reduction in the number of sessions required to reach criterion level. This study provides the first empirical evidence that the improved characteristics of mules may be extended from physical attributes to cognitive function.     

Effect of context on perception of emotion among psychiatric patients

The purpose of this research was to examine the extent to which verbal statements of context influence psychiatric patients' perception of photographs of emotion (fear, anger, sadness, and happiness). The major findings showed that, when photographs were paired congruently with context statements, there were significant changes in agreement among subjects on two of the four emotion stimuli. There was significantly less agreement on the meaning of facial expressions when the stimuli for fear, anger, and happiness were accompanied by incongruent verbal statements than when they were viewed alone. These data appear to have implications for practitioners working with this population.     

Progamming time in serial tapping responses as a function of pathway constraint

Summary This study varied the accuracy demand within a linear series of targets to investigate the effect of movement-pathway constraints on response-programming time. Sidaway, Christina, and Shea (1988) have suggested that constraints placed upon movement initiation by the demand for response precision may play an important role in determining the length of the programming process. By varying the subtended angles of a series of three targets, this experiment tested the specific prediction of Sidaway et al. that programming time may be a function of the target, within a line of targets, that subtends the smallest angle at the start position. It is this target that demands the greatest precision in the movement pathway. Subjects participated in a series of conditions in which the size and placement of the target that imposed the maximal constraint was varied. In each condition the subjects were required to strike a series of three targets with a stylus in a simple reaction-time paradigm. Analysis of the reaction-time results revealed a significant effect of size of constraint, but no effect of position of constraint. Analysis of the movementtime data dispelled movement-duration and movement-velocity interpretations of the results and intimated a possible online trajectory-correction process.Portions of these data were first presented at the Annual Meeting of the Psychonomic Society in Atlanta, Georgia, November 1989.     

Assessing alexithymia and related emotional ability constructs using multiple methods: interrelationships among measures

This study examined relationships among various measures of emotional ability reflecting different methods of assessment: self-report, clinical interview, collateral report, and emotion-relevant performance. On 140 young adults, the authors assessed self-reported alexithymia, emotional approach coping, and trait metamood skills; observer-reported alexithymia; interviewer-rated alexithymia; emotional awareness in response to vignettes; and emotional intelligence test performance. There were moderate magnitude correlations among the self-report measures, but correlations among other measures were relatively low. Confirmatory factor analyses supported a 3-factor model in which explicit self, implicit self, and explicit other measures were differentiated. These emotional ability measures do not form a unitary construct but differ as a function of the person providing the information and whether the measure is explicit or implicit.     

Reimagining gender in psychology: What can critical psychology offer?

In this article, I argue that gender is a complex sociocultural construct, yet how gender is accounted for in psychological research is limited. Specifically, psychologists conflate sex with gender, rely on quantifying gender differences and, by implication, conceptualise gender as merely a participant characteristic. To illustrate, I apply this viewpoint to the topic of gender differences in tobacco use/cessation using on a feminist quality appraisal tool. I show how these three issues promote the narrow study of sex/gender differences, despite problems surrounding this inquiry, and reduce insights into the intersection of gender and behaviour. To offer a way forward for psychology, I describe how a critical psychology perspective attends to the complexities of gender and its influence on behaviour. I showcase diverse ways of attending to gender as a sociocultural construct, inviting psychologists to engage with, and reflect on, their gender analyses.     

Antecedents of Business Opportunity Identification and Innovation: Investigating the Interplay of Information Processing and Information Acquisition

Building on conceptual frameworks of entrepreneurial discovery, we argue that active information search compensates for a lack of entrepreneurial experience and enhances the effects of divergent thinking and general mental ability (GMA) on opportunity identification. We sampled 100 business owners in South Africa. Results confirmed the hypothesised moderating effects of active information search on the relationships of entrepreneurial experience and divergent thinking on opportunity identification. Furthermore, we found direct effects of opportunity identification and conditional indirect effects of divergent thinking on innovativeness of product/service innovations. Our findings suggest that a joint examination of entrepreneurial experience and divergent thinking with active information search helps to better understand opportunity identification.     

Researching stigma as an outsider: considerations for qualitative outsider research

In this article, we discuss a number of important considerations that we have encountered in the process of researching health stigma topics as “outsiders”: researchers (personally) unfamiliar with the experience or topic under study. In particular, we discuss the importance of the following: a reflective stance, challenging negative representations, flexible and sensitive recruitment strategies, validating experiences of stigma, and participant control and power. We see these points as particularly important in the context of researching stigma as outsiders, where our privilege may contribute to unhelpful, narrow, de-politicized or overly simplistic representations of particular “groups” or experiences. We share these considerations in hope of assisting other researchers to reflect on, and articulate, how they negotiate their positionings within their research and the ways in which they shape and construct the research agenda and, by implication, the people or topics under examination.
