Online response-selection and the attentional blink: Multiple-processing channels

Robust interference often arises when multiple targets (T1 and T2) are discriminated in rapid succession (the attentional blink or AB). The AB has been observed for a wide range of stimuli, and is often thought to reflect a central capacity limitation in working memory consolidation, attentional engagement, and/or online response selection. However, recent evidence challenges the existence of unitary bottleneck during postperceptual processing. Awh et al. (2004 Awh, E., Serences, J., Laurey, P., Dhaliwal, H., van der Jagt, T. and Dassonville, P. 2004. Evidence against a central bottleneck during the attentional blink: Multiple channels for configural and featural processing. Cognitive Psychology, 48(1): 95–126.  [Google Scholar]) found no AB interference when a digit target preceded a face target, presumably because these stimuli could be processed by means of separable processing channels. Using a modified AB procedure, recent studies have also demonstrated that speeded response selection of T1 leads to an AB effect for T2 identification, supporting the conclusion that response selection induces the same processing limitations that typically gives rise to an AB. The present research tests this hypothesis by examining the effects of response selection on the identification of faces. Although we replicated previous demonstrations that online response selection of a digit disrupts the identification of T2 letters, we found no interference in the identification of T2 faces. However, robust AB interference was once again observed when a speeded response to a T1 face was required, confirming that faces are not simply immune to central interference. These results dispute the existence of a unitary postperceptual capacity limitation that gives rise to the AB.     

The State School as a Social System

Present research attempted to demonstrate the effect of response delay and the presence or absence of the experimenter on the performance of nonreinforced imitative behaviors in retarded children. A multiple baseline design, counterbalanced for conditions, was used. The results indicated that the degree of control exercised by the experimenter's presence or absence was partially determined by the response delay. Other variables that may have affected the imitative performance were (a) other nonimitative behaivors displayed by the subject(s); (b) additional stimuli generated by the experimenter; and (c) the subject's pre-experimental history with the experimenter.     

A developmental approach to treating dual-career couples

Abstract

While skills development may help some dual-career couples, for others such methods may result in feelings of frustration until certain developmental difficulties are resolved. This article: 1) addresses some problem areas that dual-career couples encounter; 2) reviews proposed solutions for these problems; 3) specifies the necessary personal requirements for mastering these solutions; and 4) suggests some of the unresolved developmental conflicts that can interfere with such mastery. The list of conflicts, proposed solutions, and typical impeding developmental difficulties is not meant to be exhaustive. Rather, this article is intended to convey a way of conceptualizing “problems surrounding problem solving” for dual-career couples.     

Are individual differences in appetitive and defensive motivation related? A psychophysiological examination in two samples

Appetitive and defensive motivation account for a good deal of variance in personality and mental health, but whether individual differences in these systems are correlated or orthogonal has not been conclusively established. Previous investigations have generally relied on self-report and have yielded conflicting results. We therefore assessed the relation between psychophysiological indices of appetitive and defensive motivation during elicitation of these motivational states: specifically, frontal electroencephalogram asymmetry during reward anticipation and startle response during anticipation of predictable or unpredictable threat of shock. Results in a sample of psychopathology-free community members (n=63), an independent sample of undergraduates with a range of internalising symptoms (n=64), and the combination of these samples (n=127) revealed that differences in responding to the two tasks were not significantly correlated. Average coefficients approached zero in all three samples (community: .04, undergraduate: ?.01, combined: .06). Implications of these findings for research on normal and abnormal personality are discussed.     

Chronic PTSD Treated With Metacognitive Therapy: An Open Trial

This paper reports on an open trial of metacognitive therapy (MCT) for chronic PTSD. MCT does not require imaginal reliving, prolonged exposure, or challenging of thoughts about trauma. It is based on an information-processing model of factors that impede normal and in-built recovery processes. It is targeted at modifying maladaptive styles of worry/rumination and attention so that emotional processing can proceed spontaneously. Eleven out of 13 patients with a mean duration of PTSD of 19.5 months completed treatment. Therapists followed the treatment manual by Wells and Sembi (2004b). Self-report measures of PTSD symptoms, anxiety and depression, and assessor ratings of PTSD were administered at pre- and posttreatment, and at 3- and 6-month follow-up. Treatment appeared to result in large and significant improvements on all measures of PTSD and general measures of anxiety and depression. Statistically significant treatment gains were maintained at 3- and 6-month follow-up. Jacobson's criteria for recovery showed that 90% of patients were recovered at posttreatment. At 6-month follow-up approximately 89% were recovered or reliably improved. Results suggest that MCT could be highly effective and extend evidence of its applicability to more treatment-resistant chronic PTSD cases. Comparisons against other active interventions are now clearly indicated.     

Cognitive content-specificity in future expectancies: role of hopelessness and intolerance of uncertainty in depression and GAD symptoms

The present study examined cognitive content-specificity in future-event predictions associated with symptoms of depression and generalized anxiety disorder (GAD). College undergraduates (N=284) completed measures of depression, GAD, and rated their certainty that a given set of positive and negative outcomes were or were not likely to happen in their future. Participants also completed measures of hopelessness and intolerance of uncertainty (IU). Individuals (N=263) completed the same measures again 6 weeks later. Certainty in an absence of positive future outcomes was associated with symptoms of depression but not GAD, and hopelessness mediated this relationship - concurrently and when examining change scores over 6 weeks. Certainty in negative outcomes was concurrently associated with both symptoms of depression and GAD, and hopelessness partially mediated these relationships. IU predicted concurrent increases in depression and GAD symptoms, and negative-outcome certainty partially mediated the IU-depression but not the IU-GAD symptom relationship. Change in certainty did not mediate the relationship between changes in IU and GAD symptoms but partially mediated the relationship between change in IU and depression symptoms over time. Hopelessness appears to play a unique role in the relationship between reduced anticipation of positive future outcomes and depression. Although less clearly suggested by the data, IU may contribute to both depression and GAD symptoms but may do so through different pathways.     

Merely Activating the Concept of Money Changes Personal and Interpersonal Behavior

ABSTRACT— Money plays a significant role in people's lives, and yet little experimental attention has been given to the psychological underpinnings of money. We systematically varied whether and to what extent the concept of money was activated in participants' minds using methods that minimized participants' conscious awareness of the money cues. On the one hand, participants reminded of money were less helpful than were participants not reminded of money, and they also preferred solitary activities and less physical intimacy. On the other hand, reminders of money prompted participants to work harder on challenging tasks and led to desires to take on more work as compared to participants not reminded of money. In short, even subtle reminders of money elicit big changes in human behavior.     

Retrospective dream components and musical preferences

Retrospective dream components endorsed on the KJP Dream Inventory were correlated with those on the Short Test of Musical Preference for 68 graduate students in counseling psychology (11 men). Among 40 correlations, 6 were significant between preferences for Heavy Metal and Dissociative avoidance dreams (.32), Dreaming that you are dreaming (.40), Dreaming that you have fallen unconscious or asleep (.41), Recurring pleasantness (.31), and Awakening abruptly from a dream (-.31); between preferences for Rap/Hip-Hop and Sexual dreams (.27); and between preferences for Jazz and Recurring pleasantness in dreams (.33). Subjects preferring Classical music reported a higher incidence of Dreams of flying (.33) and rated higher Discontentedness in dreams (-.26). The meaning of these low values awaits research based on personality inventories and full dream reports.
