Effects of trait anger and anger expression style on competitive attack responses in a wartime prisoner’s dilemma game

We assessed the role of trait anger and anger expression style on competitive/aggressive decision making and responding. In a 100‐trial iterated Prisoner’s Dilemma (IPD), with instructions to simulate wartime interactions, competition/aggression was defined as “attacking the opponent,” and “waiting for troop reinforcements” was the noncompetitive alternative response. Prior to play, 92 university student players completed the State‐Trait Anger Expression Inventory. They were then paired to play the IPD against partners of similar or dissimilar trait anger levels. At postplay, the State Anger scale was readministered. Results showed significant preplay to postplay increases in state anger, with greater increases shown by high trait anger players. Thus, high trait anger players were especially subject to arousal. Players in the high trait anger group made more competitive/attack responses, and they were more likely to do so when paired with a high trait anger partner. As a result of the high level of competitive/aggressive play, both groups ended with a negative troop count. Trait anger as a general personality temperament was predictive of state anger, competitive/attack responses, and the number of trials before a retaliation was made. The expressive style of anger‐control was also related to manner of play. Trait anger had strong direct and indirect effects through anger control on the number of competitive attack responses. It was concluded that trait anger, especially trait anger/temperament, and anger control difficulties may be toxic personality factors in decision making and competitive behavior. Aggr.

Overcoming Procrastination: The Effect of Implementation Intentions1

A hypothesized solution for procrastination is the formation of an implementation intention ( Van Eerde, 2000 ). University students (N = 152) were assessed using the Aitken Procrastination Inventory ( Aitken, 1982 ) and were asked to report to an experiment. Half of the participants formed implementation intentions to attend. An odds ratio indicated that participants who formed implementation intentions were nearly 8 times more likely to keep their appointments than those who did not. Low procrastinators reported more often for the experiment than did high procrastinators (Low = 49.4%; High = 30.1%), χ²(1, N = 152) = 5.84, p < .016. The interaction between implementation intentions and procrastination was not significant, χ²(1, N = 152) = 0.28, p < .60.     

Decision noise may mask criterion shifts: Reply to Balakrishnan and MacDonald (2008)

J. D. Balakrishnan and J. A. MacDonald (2008) argue that RTbased measures of signal detection processes provide evidence against signal detection theory’s notion of a flexible decision criterion. They argue that this evidence is immune to the alternative explanation proposed by S. T. Mueller and C. T. Weidemann (2008), that decision noise may mask criterion shifts. We show that noise in response times can produce the same effects as are produced by noise in confidence ratings. Given these results, the evidence is not sufficient to categorically reject the notion of a flexible response policy implemented through shifts in a decision criterion. nt]mis|This research was supported in part by a postdoctoral fellowship to C.T.W. from the German Academic Exchange Service (DAAD).     

Understanding the social emotional practices of therapists

Emotions are central to the therapy process and skilful use by therapists of client emotion is an essential catalyst to client change. However, the contribution of emotion to the therapy process and how therapists’ social emotional skills are incorporated into psychological practice is still unclear. Using a statistical method for mapping psychological constructs, therapists’ social emotional skills were transformed into a “map” with three spatial dimensions, which was supported by comparative reliability checks. The nature of social emotional skills was further investigated by administering a Q-Sort of emotional practice items to 47 therapists. Ten highly applicable clusters of social emotional skills across seven style patterns with therapists were identified. Tentative links were drawn between demographic data and both clusters and therapist styles. These findings suggest therapists’ social emotional skills can be organised into meaningful clusters and that therapists can be styled according to their responses across these clusters. Furthermore, gaps identified in the model suggest possible “blind spots” in the literature. The implications of these findings are significant for training and practice.     

Integrating Positive Psychology Into Counseling: Why and (When Appropriate) How

Counseling psychology has a historical commitment to enhancing human strengths, a focus that has enjoyed broader interest with the recent emergence of positive psychology. However, theory and evidence linking strength enhancement to counseling goals are still relatively nascent. The authors outline rationales and practical strategies for integrating strength promotion into counseling practice. Forgiveness and spirituality are used as examples illustrating the opportunities, limitations, and challenges of making strength promotion practical (and reimbursable) in counseling.     

Seemingly Anomalous WISC-IV Full Scale IQ Scores in the American and Canadian Standardization Samples

The American and Canadian standardization samples for the fourth edition of the Wechsler Intelligence Scale for Children were used to ascertain the prevalence of “seemingly anomalous” Full Scale IQ (FSIQ) scores for all possible sums of scaled scores combinations of the Verbal Comprehension Index, Perceptual Reasoning Index, Working Memory Index, and Processing Speed Index. About 1% of FSIQ scores in both samples were anomalous (that is, fell outside the range of the four indices). Interestingly, the prevalence of anomalous scores was higher at the extremes of the FSIQ distribution. Moreover, anomalous FSIQ scores occurring above or below the mean of the FSIQ distribution (that is, 100) were larger or smaller, respectively, than any of the four indices. Furthermore, if the range of the four indices did contain the FSIQ (the non-anomalous case), when the FSIQ was below or above 100 it tended to be located distally in the half-segment of the range furthest below or above 100, respectively. A non-technical intuitive analogy from Olympic sports and a statistical explanation for the findings are provided. Important implications for practitioners are also presented.

Frames and brains: elicitation and control of response tendencies

Using magnetic resonance imaging, De Martino and colleagues investigated the neural signature that is associated with decisions between small sure amounts of money and large riskier amounts when the framing of the outcomes is varied. We interpret their results within a dual-system framework, in which different frames evoke distinct emotional responses that different individuals can suppress to various degrees. The study advances the integration of brain imaging results into cognitive theory.     

Hinge versus twist: the effects of 'reference surfaces' and discontinuities on stereoscopic slant perception

Stereoscopic slant perception around a vertical axis (horizontal slant) is often found to be strongly attenuated relative to geometric prediction. Stereo slant is much greater, however, when an adjacent surface, stereoscopically in the frontal plane, is added. This slant enhancement is often attributed to the presence of a 'reference surface' or to a spatial change in the disparity gradient (introducing second and higher derivatives of disparity). Gillam, Chambers, and Russo (1988 Journal of Experimental Psychology: Human Perception and Performance 14 163-175) questioned the role of these factors in that placement of the frontal-plane surface in a direction collinear with the slant axis (twist configuration) sharply reduced latency for perceiving slant whereas placing the same surface in a direction orthogonal to the slant axis (hinge configuration) had little effect. We here confirm these findings for slant magnitude, showing a striking advantage for twist over hinge configurations. We also examined contrast slant measured on the frontal-plane surface in the hinge and twist configurations. Under conditions where test and inducer surfaces have centres at the same depth for twist and hinge, we found that twist configurations produced strong negative slant contrast, while hinge configurations produced significant positive contrast or slant assimilation. We conclude that stereo slant and contrast effects for neighbouring surfaces can only be understood from the patterns and gradients of step disparities present. It is not adequate to consider the second surface merely as a reference slant for the first or as having its effect via a spatial change in the disparity gradient.
