Reducing Identity Distress: Results of an Identity Intervention for Emerging Adults

Emerging adulthood is a transitional period between adolescence and adulthood where positive and negative life trajectories tend to diverge, with issues surrounding identity formation playing a key role. The present study evaluated the Miami Adult Development Project, a self-facilitated identity-focused intervention. The sample consisted of 141 emerging adults (19?29 years old; M = 23.08) who completed pretest and posttest assessments. Results indicated participation in the intervention relative to the comparison group was associated with lower levels of identity distress and higher levels of well-being via the reduction of identity distress and the development of a consolidated identity (commitment and synthesis). The present study provides evidence for the effectiveness of positive identity interventions during emerging adulthood.     

The effect of persistent posttraumatic stress disorder symptoms on executive functions in preadolescent children witnessing a single incident of death

We compared executive functions (EFs) of traumatized preadolescent children with and without marked posttraumatic stress disorder (PTSD) symptoms to the performance of a nontraumatized control group, and examined the relationships between EF deficits and functional status in traumatized preadolescent children. Fifty-one preadolescent children who had witnessed a death at school 30 months prior (26 with marked PTSD symptoms and 25 without) and 30 healthy controls who had not been traumatized participated. EFs were examined using the Comprehensive Attention Test (CAT). The functional state of traumatized children was measured by the Parent Report Form-Children's Health and Illness Profile-Children's Edition (PRF-CHIP-CE). The traumatized children, regardless of status of PTSD symptomatology, showed poorer working memory performance than nontraumatized healthy controls. The traumatized children with marked PTSD symptoms performed more poorly on measures of interference control compared to those children without marked PTSD symptoms. Lower levels of EFs were associated with lower risk avoidance and diminished academic achievement in traumatized children. These results indicate that an inhibitory control deficit is specifically associated with the current PTSD symptoms but not with trauma exposure per se.     

Fitting an ex-Gaussian function to examine costs in event-based prospective memory: Evidence for a continuous monitoring profile

Event-based prospective memory (PM) tasks require individuals to remember to perform a deferred action when a target event occurs. PM task requirements can slow ongoing task responses on non-target trials (‘costs’) under conditions where the defining features of targets are non-focal to the ongoing task, which is indicative that individuals have allocated some form of cognitive control process to the PM task. Recent fits of the ex-Gaussian mathematical function to non-target trial response distributions by prior studies have indicated that these control processes are transiently allocated. In the current paper, fits of the ex-Gaussian function to data reported by Loft and Humphreys (2012) demonstrate a shift in the entire response time distribution (μ) and an increase in skew (τ) for a non-focal PM condition required to remember to make a PM response if presented with category exemplars, compared to a control condition. This change in μ is indicative of a more continuous PM monitoring profile than that reported by prior studies. In addition, within–subject variability in μ was reliably correlated with PM accuracy, suggesting that these control processes allocated on a regular basis were functional to PM accuracy. In contrast, when the ongoing task directed attention to the defining features of targets (focal PM) there was a trend level increase in μ, but the within–subject variability in μ was not correlated with PM accuracy, consistent with the theoretical premise that focal PM tasks are not as dependent on cognitive control as non-focal PM tasks.

Attending to music decreases inattentional blindness

This article investigates how auditory attention affects inattentional blindness (IB), a failure of conscious awareness in which an observer does not notice an unexpected event because their attention is engaged elsewhere. Previous research using the attentional blink paradigm has indicated that listening to music can reduce failures of conscious awareness. It was proposed that listening to music would decrease IB by reducing observers’ frequency of task-unrelated thoughts (TUTs). Observers completed an IB task that varied both visual and auditory demands. Listening to music was associated with significantly lower IB, but only when observers actively attended to the music. Follow-up experiments suggest this was due to the distracting qualities of the audio task. The results also suggest a complex relationship between IB and TUTs: during demanding tasks, as predicted, noticers of the unexpected stimulus reported fewer TUTs than non-noticers. During less demanding tasks, however, noticers reported more TUTs than non-noticers.     

There's more to taste in a coloured bowl

The flavour and pleasantness of food and drinks are affected by their colour, their texture or crunch, and even by the shape and weight of the plate or glass. But, can the colour of the bowl also affect the taste of the food it contains? To answer this question we served popcorn in four different coloured bowls, and participants rated sweetness, saltiness, and overall liking. The sweet popcorn, in addition to being sweet, was perceived as saltier when eaten out of a coloured (as compared to a white) bowl, and vice versa for the salty popcorn. These results demonstrate that colour in bowl design can be used to elicit perceptions of sweetness and saltiness in real foods.     

Are social prediction errors universal? Predicting compliance with a direct request across cultures

Previous research conducted in the United States has demonstrated that help-seekers fail to appreciate the embarrassment and awkwardness (i.e., social costs) targets would experience by saying “no” to a request for help. Underestimation of such social costs leads help-seekers to underestimate the likelihood that others will comply with their requests. We hypothesized that this error would be attenuated in a collectivistic culture. We conducted a naturalistic help-seeking study in the U.S. and China and found that Chinese help-seekers were more accurate than American help-seekers at predicting compliance. A supplementary scenario study in which we measured individual differences in collectivistic and individualistic orientations within a single culture provided converging evidence for the association between collectivism and expectations of compliance. In both cases, the association between collectivism (culturally defined or measured) and predicted compliance was mediated by participants' ratings of the social costs of saying “no”.     

The negative self-portrayal scale: development, validation, and application to social anxiety

The Negative Self-Portrayal Scale (NSPS) is a new questionnaire designed to assess the extent to which individuals are concerned that specific self-attributes they view as being deficient will be exposed to scrutiny and evaluation by critical others in social situations. These concerns have been proposed to drive symptoms of social anxiety and account for individual differences in social fears and avoidance behaviors (Moscovitch, 2009). Here, we introduce the NSPS and examine its factor structure and psychometric properties across two large samples of North American undergraduate students with normally distributed symptoms of social anxiety. Exploratory and confirmatory factor analyses supported a 3-factor solution representing concerns about (a) social competence; (b) physical appearance; and (c) signs of anxiety. The NSPS was found to have good internal consistency and test-retest reliability, strong convergent validity, and adequate discriminant validity. In addition, NSPS total scores accounted for a significant proportion of unique variance in self-concealment (i.e., safety) behaviors over and above established symptom measures of social interaction anxiety, social performance anxiety, and depression. Results are discussed in relation to theoretical models of social anxiety and the potential utility of the NSPS for both clinical research and practice.     

The development of visual working memory capacity during early childhood

The change detection task has been used in dozens of studies with adults to measure visual working memory capacity. Two studies have recently tested children in this task, suggesting a gradual increase in capacity from 5 years to adulthood. These results contrast with findings from an infant looking paradigm suggesting that capacity reaches adult-like levels within the first year. The current study adapted the change detection task for use with children younger than 5 years to test whether the standard version of the task was too difficult and may have underestimated children's capacity. Results showed that 3- and 4-year-olds could successfully complete this modified task and that capacity increased roughly linearly, from 2 or 3 items during this period to 3 or 4 items between 5 and 7 years. Furthermore, performance did not differ significantly between the modified version and a replication of the standard version with 5- and 7-year-olds. Thus, there is no evidence that previous research with the change detection task underestimated children's capacity. Further research is needed to understand how performance relates across the infant looking task and change detection to provide a more complete picture of visual working memory capacity over development.
