Recall and recognition of order and item information in probed running memory, as a function of IQ

Two experiments were designed to test the possibility that correlations between IQ and probed serial running memory depend on IQ-related individual differences in the retention of order information in short-term memory. In Experiment I, correlations were obtained regardless of whether instructions emphasized serial recall or free recall. In Experiment II, a significant correlation between IQ and performance was obtained in a recognition test for very recent item information, but not in a recognition test for very recent order information. These data together with a theoretical analysis of the operations involved in the tasks, led to the conclusion that the correlations reflected individual differences in the capacity to access specified sets of items in very short-term memory.     

Sequential cotherapy of groups for training and clinical care

Cotherapy has often been used as the leadership model in group therapy. The literature is full of contradictory data and impressions as to the efficacy of this model. In this article a new form of cotherapy is presented which may offer some of the assets attributed to the cotherapy leadership model while at the same time reducing some of the liabilities. Sequential cotherapy refers to cotherapy when each of the therapists leads sequentially rather than at the same time. The pros and cons of such an approach are discussed from both the perspectives of training new group therapists and of service to patients in groups.Dr. Rutan and Mrs. Alonso are members of the faculty of Harvard University Medical School and share responsibility for training psychiatric residents in group therapy at Massachusetts General Hospital, Boston, Massachusetts.     

Female aggression as a function of attitudes toward women

The aggressive behavior of female subjects who held either liberal or traditional beliefs concerning the role of women in modern society was investigated as a function of provocation by traditional or liberal male opponents. Traditional female subjects responded more aggressively than liberal females. The male opponent's attitude had no effect on female aggression.This article is based on an honors thesis submitted to the Honors and Experimental College of Kent State University by the second author.     

Suicide Attempt Self-Injury Interview (SASII): development, reliability, and validity of a scale to assess suicide attempts and intentional self-injury

The authors describe the development of the Suicide Attempt Self-Injury Interview (SASII), an instrument designed to assess the factors involved in nonfatal suicide attempts and intentional self-injury. Using 4 cohorts of participants, authors generated SASII items and evaluated them with factor and content analyses and internal consistency statistics. The final measure was assessed for reliability and validity with collateral measures. The SASII assesses variables related to method, lethality and impulsivity of the act, likelihood of rescue, suicide intent or ambivalence and other motivations, consequences, and habitual self-injury. The SASII was found to have very good interrater reliability and adequate validity.     

Factor structure of the Chinese version of the Geriatric Depression Scale

Depression is common in patients following stroke and has been found to be related to the degree of functional disability, recovery and engagement in rehabilitation. Consequently, screening for depression is crucial in this group in order to facilitate the delivery of appropriate psychological support. The current study sought to determine key psychometric properties of the Chinese version of the Geriatric Depression Scale (GDS) in this group. Three versions of the GDS were evaluated, these being the 30-item original measure (GDS-30), the short-form version comprising 15 items (GDS-SF) and a recently developed innovative four-item version (GDS-4). Confirmatory factor analysis revealed the GDS-30 and GDS-SF to offer an acceptable fit to data suggesting utility of these measures for screening. However, the GDS-4 offered a poor fit to the data, suggesting this measure was an inadequate measure of depression in this clinical group. Further, though GDS-30 and GDS-SF measures revealed good internal consistency, the performance of the GDS-4 was marginal. However, all GDS-derived measures demonstrated excellent convergent and divergent validity. It is concluded that the GDS-30 is a useful and appropriate screening instrument in this group. Further, the GDS-SF shows promise in terms of development as a multidimensional measure of depression that may have predictive and outcome monitoring potential. The psychometric shortcomings of the GDS-4 strongly suggest that this measure is unsuitable for screening in this clinical group.     

Efficiency of visual information processing in children at-risk for dyslexia: habituation of single-trial ERPs

To investigate underlying learning mechanisms in relation to the development of dyslexia, event-related potentials to visual standards were recorded in five-year-old pre-reading children at-risk for familial dyslexia (n=24) and their controls (n=14). At the end of second grade the children aged 8 years were regrouped into three groups according to literacy level and risk factor. Single-trial analyses revealed N1 habituation in the normal-reading controls, but not in the normal-reading at-risks, and a N1 amplitude increase in the group of poor-reading at-risks and poor-reading controls. No P3 habituation was found in either group. The normal-reading at-risk group exhibited the longest N1 and P3 latencies, possibly compensating for their reduced neuronal activity during initial information extraction. In contrast, the poor-reading group only showed prolonged P3, and their increase in (initial small) N1 amplitude together with normal N1 latencies, suggests inefficient processing in an early time window, which might explain automatisation difficulties in dyslexic readers.     

Comparing judgments of stuttering made by students, clinicians, and highly experienced judges

Purpose: The purpose of this study was to compare judgments of stuttering made by students and clinicians with previously available judgments made by highly experienced judges in stuttering. Method: On two occasions, 41 university students and 31 speech-language pathologists judged the presence or absence of stuttering in each of 216 audiovisually recorded 5-s intervals of the speech of adults who stutter. Intrajudge and interjudge agreement were calculated, and comparisons were made to judgments previously made about the same recordings by 10 highly experienced judges of stuttering. Results: Students and clinicians showed similar and relatively high levels of intrajudge and interjudge agreement, but both students and clinicians identified less than half as much stuttering as the highly experienced judges had identified. Conclusions: These results replicate previous findings of high agreement coexisting with low accuracy in students’ judgments of stuttering, extending those findings to show that similar problems are evident in judgments made by practicing clinicians. Implications include the need for explicit stuttering judgment training programs for both students and practicing clinicians.

Educational objectives: After reading this article, the reader will be able to: (1) describe different methods for identifying stuttering and possible problems associated with each method; (2) describe two different methods for reporting interjudge reliability; (3) describe how the identification of stuttering differs for student, clinician, and highly experienced judges.     

Toward a formal theory of flexible spatial behavior: geometric category biases generalize across pointing and verbal response types

Three experiments tested whether geometric biases--biases away from perceived reference axes--reported in spatial recall tasks with pointing responses generalized to a recognition task that required a verbal response. Seven-year-olds and adults remembered the location of a dot within a rectangle and then either reproduced its location or verbally selected a matching choice dot from a set of colored options. Results demonstrated that geometric biases generalized to verbal responses; however, the spatial span of the choice set influenced performance as well. These data suggest that the same spatial memory process gives rise to both response types in this task. Simulations of a dynamic field model buttress this claim. More generally, these results challenge accounts that posit separate spatial systems for motor and verbal responses.     

Anger and guilt about ingroup advantage explain the willingness for political action

Three studies examined non-Aboriginal Australians' guilt and anger about their ingroup's advantage over structurally disadvantaged Aborigines. Study 1 showed that participants who perceived their ingroup as relatively advantaged perceived this inequality as unfair and felt guilt and anger about it. Anger, and to a lesser degree guilt, predicted the willingness to engage in political action regarding ingroup advantage. Study 2 showed both guilt and anger to be relatively self-focused because both were associated with appraising the ingroup's (rather than the government's) discrimination as responsible for ingroup advantage. Study 3 examined on participants especially willing to engage in political action to bring about systemic compensation to Aborigines. Anger about ingroup advantage was a potent predictor. Although guilt was associated with the abstract goal of systemic compensation, guilt did not explain willingness for political action. Results underline the importance of examining specific group-based emotions in intergroup relations.
