Cognitive implications of facilitating echoic persistence

Seventeen participants performed a tone-pattern-matching task at different presentation levels while concurrently engaged in a simulated-driving task. Presentation levels of 60, 65, and 70 dBC (SPL) were combined factorially with tone-matching delays of 2, 3, and 4 sec. Intensity had no effect on performance in single-task conditions and short-delay conditions. However, when the participants were engaged concurrently in the driving task, a significant interaction between presentation level and delay was observed. In the longest delay condition, the participants performed the tone-pattern-matching task more efficiently (more quickly and without additional errors) as presentation intensity increased. These findings demonstrate the interaction between sensory and cognitive processes and point to a direct-intensity relationship where intensity affects the persistence of echoic memory. Implications for facilitating auditory processing and improving auditory interfaces in complex systems (i.e., transportation environments), particularly for older and hearing-impaired listeners, are discussed.     

Cutting stress off at the pass: reducing vigilance and responsiveness to social threat by manipulating attention

Personality processes relating to social perception have been shown to play a significant role in the experience of stress. In 5 studies, the authors demonstrate that early stage attentional processes influence the perception of social threat and modify the human stress response. The authors first show that cortisol release in response to a stressful situation correlates with selective attention toward social threat. Second, the authors show in 2 laboratory studies that this attentional pattern, most evident among individuals with low self-esteem, can be modified with a repetitive training task. Next, in a field study, students trained to modify their attentional pattern to reduce vigilance for social threat showed lower self-reported stress related to their final exam. In a final field study with telemarketers, the attentional training task led to increased self-esteem, decreased cortisol and perceived stress responses, higher confidence, and greater work performance. Taken together, these results demonstrate the impact of antecedent-focused strategies on the late-stage consequences of social stress.     

The Latent Structure of the Center for Epidemiological Studies-Depression Scale

Taxometric analyses were used to assess the latent structure of depressive symptoms as measured by the Center for Epidemiological Studies Depression (CES-D) scale. Participants were 3,395 college students enrolled in Introductory Psychology classes at a mid-size university. Analyses included data simulation strategies to assure that the data was appropriate for interpreting skewed indicators and small putative taxa. Four indicators (depressed mood, positive affect, somatic, and interpersonal symptoms) were derived from principal components analysis. Taxometric analyses indicated that distributions of the four CES-D factor based indicators were dimensional. Results are consistent with a continuity model of the latent structure of questionnaire measures of depressive symptoms in this young adult population, of which approximately 15% scored above the clinical cut-point for the CES-D scale.     

Computer game associating self-concept to images of acceptance can reduce adolescents' aggressiveness in response to social rejection

The experience of social rejection can lead to an aggressive response. However, the ability to maintain a sense of social connection may reduce the likelihood of this type of response. We tested a computer-based intervention designed to use simple learning principles to boost the sense of social connection and acceptance. Adolescents aged 9–15 (n=138) first completed a conditioning game on computer that repeatedly paired their own name with images of social acceptance (versus a control condition with no systematic pairing), and subsequently reported how aggressively they would behave in response to being rejected by a peer. Those completing the self-acceptance conditioning (particularly those low in self-esteem) reported less aggressive feelings and intentions.     

On mean‐sigma estimators and bias

When two test forms measure the same construct but are independently modelled using item response theory, the two forms’ respective metrics cannot be assumed to be equivalent. Thus, before comparing parameter estimates across forms, a linear transformation must be applied to at least one form's scale. The mean‐sigma method is a well‐known procedure for estimating this adjustment when a common set of items appears on both forms. In this paper, I show both analytically and empirically (through a small simulation study) that the mean‐sigma estimators of the transformation constants are biased. While this systematic error was modest relative to random error under the conditions studied here, it is nevertheless intrinsic and its magnitude is conditional on extrinsic design features that include the number of anchor items and the quality of their difficulty estimates.     

Self-esteem and the Dual Processing of Interpersonal Contingencies

Social cognitive research has shown that individuals with low self-esteem exhibit contingency expectations involving interpersonal acceptance and rejection (e.g., If I fail, then I will be rejected). We examined whether the processing differences between low and high self-esteem individuals would be evident in their most spontaneous reactions, or only in relatively deliberate responses. A lexical decision task measured people's reaction times to positive or negative interpersonal words, following success or failure primes. The stimulus onset asynchrony was manipulated to allow spontaneous or deliberate processing. Individuals with low self-esteem exhibited contingencies at the spontaneous level. These contingencies were not evident in individuals with high self-esteem. The findings support interpersonal models of self-esteem, and confirm that controlled, deliberate thought is not required for the activation of relational expectations.     

The company you keep: Fear of rejection in intergroup interaction

People use many cues to infer the likelihood of acceptance or rejection in intergroup interactions. Nearly all prior research has focused on personal cues directly given off by the potential interaction partner (e.g., eye contact and smiling). However, we argue that in the context of intergroup interactions, individuals may be especially sensitive to broader social cues, such as an interaction partner's social network. Across three experiments we explored differences in White participants' evaluations of a smiling Black man presented with a Black or White friend. When this Black man was featured with a Black friend, White participants reported greater rejection concerns and a greater inclination to reject this Black man compared to when he was featured with a White friend (Experiments 1-3) or featured alone (Experiment 2). Furthermore, when participants received a simple intervention designed to buffer against social rejection, the race of the Black man's friend no longer influenced participants' interests in befriending the Black man (Experiment 3). This research demonstrates the power of friendships in interracial interactions and provides evidence for a simple intervention to reduce the weight of rejection concerns in interracial interactions.     

How regulatory focus impacts the process-by-outcome interaction for perceived fairness and emotions

Judgments of fairness take into account at least two pieces of information—the outcome received and the process by which the outcome was assigned. Generally speaking, low levels of fairness are apt to be reported when the outcome is unfavorable and the allocation process is deemed inappropriate. In this study, we investigate how regulatory focus theory can further our understanding of the process by outcome interaction. Specifically, when individuals are working to add to their earnings (a promotion focus) the typical effect is observed. However, when individuals are focused on maintaining something that is their own (a prevention focus) the most negative emotion occurs when individuals are allocated an unfavorable outcome through a process that contains procedural safeguards.     

Examining Alternative Explanations of the Covariation of ADHD and Anxiety Symptoms in Children: A Community Study

Attention-deficit hyperactivity disorder (ADHD) is comorbid with a range of other disorders, including anxiety disorders. The aim was to examine different explanations for the covariation of these symptom domains in children according to the framework provided by (Lilienfeld, S. O. Comorbidity between and within childhood externalizing and internalizing disorders: Reflections and directions. Journal of Abnormal Child Psychology, 2003). The covariation of ADHD symptoms and anxiety symptoms were examined over a 12-month period in a community sample of 499 children aged 8-13; 91% were retained at 12-month follow-up. Dimensional assessments were conducted using questionnaires given to children, parents and teachers, with results analyzed via structural equation modeling. Positive associations between ADHD and anxiety symptoms were linked with inattention symptoms, were particularly pronounced for girls, and were linked via temperament and behavioral problems. No support for the hypothesis that ADHD symptoms predicted the development of anxiety symptoms over time or vice versa. ADHD symptoms (particularly inattention) and anxiety symptoms are covarying phenomena that are linked with an irritable temperament and disruptive behavior.
