The Effect of Delayed Responding on Stroop-Like Task Performance Among Preschoolers

Forty-four preschoolers completed 2 conditions of a Stroop-like procedure (e.g., saying “boat” for car and “car” for boat) that differed in whether a 3-s delay was imposed before responding. The test card was visible during the delay period for half of the children and occluded for the other children. Preschoolers’ interference control was significantly improved in the delay condition. There was no difference between the two delay variants (test card visible or occluded). Children were more prone to interference as testing progressed regardless of whether the delay was present. These results suggest that delays effectively reduce interference by reducing the potency of the competing response during test trials, although memory demands may moderate the effectiveness of delays.     

Role Satisfaction Mediates the Relation between Role Ambiguity and Social Loafing among Elite Women Handball Players

The aims of the study were to develop a questionnaire on self-reported social loafing (SRSLQ), and then to examine its relations with role ambiguity and role satisfaction in a sample of 110 women handball players competing at the elite level in Norway. Structural equation modeling analyses indicated that the SRSLQ was a psychometrically sound measure. In line with the expectations, role satisfaction fully mediated the positive relation between role ambiguity and self-reported social loafing: The more players experienced role ambiguity, the less satisfied they were with their role in the team, and the more social loafing they reported.     

Tracking the Lacanian unconscious in language

This paper makes two contributions to the emerging field of Lacanian discourse analysis (LDA); one, by way of theoretical exposition and a second, oriented toward the challenges of empirical analysis. In the first section of the paper, I illustrate and develop upon the elusive Lacanian notion of the unconscious structured as a language. This discussion yields a series of important ideas: the assertion that a matrix of latent significations shadows any utterance; the distinction between statement/enunciation; and the concept of repression-in-language. These concepts provide a platform for the second section of the paper which draws on textual material collected by the Apartheid Archive Project in order to demonstrate a particular procedure of LDA. This procedure entails an attention to discontinuous narrative components and the role of symbolic juxtapositions. It points, furthermore, to the value of making novel combinations of given textual elements as a way of querying what may be repressed in the text. Two important conclusions are drawn from this discussion, each of which indicates a priority for Lacanian practice. Firstly, the idea that the ongoing work of symbolic juxtaposition may be more profitable than ‘depth’ interpretations in conducting analysis. Secondly, that facilitation of lateral significations and associated significations should take priority over the aim of extracting a single over-arching message.     

Belief bias during reasoning among religious believers and skeptics

We provide evidence that religious skeptics, as compared to believers, are both more reflective and effective in logical reasoning tasks. While recent studies have reported a negative association between an analytic cognitive style and religiosity, they focused exclusively on accuracy, making it difficult to specify potential underlying cognitive mechanisms. The present study extends the previous research by assessing both performance and response times on quintessential logical reasoning problems (syllogisms). Those reporting more religious skepticism made fewer reasoning errors than did believers. This finding remained significant after controlling for general cognitive ability, time spent on the problems, and various demographic variables. Crucial for the purpose of exploring underlying mechanisms, response times indicated that skeptics also spent more time reasoning than did believers. This novel finding suggests a possible role of response slowing during analytic problem solving as a component of cognitive style that promotes overriding intuitive first impressions. Implications for using additional processing measures, such as response time, to investigate individual differences in cognitive style are discussed.     

A parametric analysis of errors of commission during discrete-trial training

We investigated the effects of systematic changes in levels of treatment integrity by altering errors of commission during error-correction procedures as part of discrete-trial training. We taught 3 students with autism receptive nonsense shapes under 3 treatment integrity conditions (0%, 50%, or 100% errors of commission). Participants exhibited higher levels of performance during perfect implementation (0% errors). For 2 of the 3 participants, performance was low and showed no differentiation in the remaining conditions. Findings suggest that 50% commission errors may be as detrimental as 100% commission errors on teaching outcomes.     

Temporal discounting predicts student responsiveness to exchange delays in a classroom token system

Typical assessments of temporal discounting involve presenting choices between hypothetical monetary outcomes. Participants choose between smaller immediate rewards and larger delayed rewards to determine how the passage of time affects the subjective value of reinforcement. Few studies, however, have compared such discounting to actual manipulations of reward delay. The present study examined the predictive validity of a temporal discounting procedure developed for use with children. Forty-six sixth-grade students completed a brief discounting assessment and were then exposed to a classwide intervention that involved both immediate and delayed reinforcement in a multiple baseline design across classrooms. The parameters derived from two hyperbolic models of discounting correlated significantly with actual on-task behavior under conditions of immediate and delayed exchange. Implications of temporal discounting assessments for behavioral assessment and treatment are discussed.     

Understanding and supporting the career implications of international assignments

International assignments represent an important form of migration in the global economy. In contrast to most other migrants, international assignees enjoy a relatively privileged position in the labor market. Authored by a diverse team of academics and practitioners, this paper draws on insights from empirical research and unpublished examples from practice to explore how international assignees can be supported before, during and after the international assignment. We move beyond the traditional expatriate cycle as a frame of reference, arguing that many of the challenges from the individual perspective are continuous, often pertinent well before and well after the assignment. We call for a reframing of career support for international assignees to reflect the reality of the experience. We propose that future studies of the impact of international assignments on career use more sophisticated methods including longitudinal studies of career trajectories and experiences of support practices.

Age-related differences in profiles of mood-change trajectories

As a group, older adults report positive affective lives. The extent to which there are subgroups of older adults whose moods are less positive, however, is unclear. Our aim in the present study was to identify and characterize different subgroups of adults who exhibit distinct trajectories of mood change across a relatively short time period. Seventy-nine young and 103 older adults continuously reported their moods while viewing emotional and neutral faces. Cluster analysis revealed four subgroups of mood-change trajectories. Both the most positive and the most negative subgroups included more older than young adults (ps < .05), suggesting that not all older adults exhibit higher positive affect than young adults. Analyses of variance revealed that the most negative group exhibited slower processing speed, more state anxiety and neuroticism, and looked less at happy faces than the other groups (ps < .05). The results are discussed from an adult developmental perspective, focusing on the increased variability of mood trajectories in the older adults and whether this is a reflection of adaptive functioning or a potential harbinger of dysfunction.     

Discrepant integration times for upright and inverted faces

Judgments of upright faces tend to be more rapid than judgments of inverted faces. This is consistent with encoding at different rates via discrepant mechanisms, or via a common mechanism that is more sensitive to upright input. However, to the best of our knowledge no previous study of facial coding speed has tried to equate sensitivity across the characteristics under investigation (eg emotional expression, facial gender, or facial orientation). Consequently we cannot tell whether different decision speeds result from mechanisms that accrue information at different rates, or because facial images can differ in the amount of information they make available. To address this, we examined temporal integration times, the times across which information is accrued toward a perceptual decision. We examined facial gender and emotional expressions. We first identified image pairs that could be differentiated on 80% of trials with protracted presentations (1 s). We then presented these images at a range of brief durations to determine how rapidly performance plateaued, which is indicative of integration time. For upright faces gender was associated with a protracted integration relative to expression judgments. This difference was eliminated by inversion, with both gender and expression judgments associated with a common, rapid, integration time. Overall, our data suggest that upright facial gender and expression are encoded via distinct processes and that inversion does not just result in impaired sensitivity. Rather, inversion caused gender judgments, which had been associated with a protracted integration, to become associated with a more rapid process.     

Self-image bias in drug use attributions

The aim was to examine the degree to which people's personal drug use affects how they perceive other drug users, with a view to investigating the possibility that drug use attributions are a function of self-image bias. University students (n = 60), categorized post hoc as drug users or nonusers, completed questionnaires assessing locus, control, and stability attributions about their own personal drug use or imagined drug use. Attributions pertaining to presented vignettes of light and heavy drug use by others were also assessed. Heavy drug use elicited the most "addicted" attributions (dispositional locus, low control, and high stability) and drug-using participants made more addicted attributions about their own personal drug use than did nonusing participants about their imagined use. Additionally, attributions made by non-drug users regarding their imagined personal drug use were similar to those they made for the light drug use described in presented vignettes. Conversely, drug users made attributions which were similar for their personal drug use and for the heavy drug-use vignette. These data lend support to conceptualizing addiction as a product of the functional attribution process-"addict" attributions being applied mainly where drug use is more problematic (heavy) and thus in need of explanation. The data also lend support to the notion that a self-image bias is operating in drug use attributions when people can identify with the behavior of others.
