Abortion and Mental Health: Evaluating the Evidence.

The authors evaluated empirical research addressing the relationship between induced abortion and womens mental health. Two issues were addressed: (a) the relative risks associated with abortion compared with the risks associated with its alternatives and (b) sources of variability in womens responses following abortion. This article reflects and updates the report of the American Psychological Association Task Force on Mental Health and Abortion (2008). Major methodological problems pervaded most of the research reviewed. The most rigorous studies indicated that within the United States, the relative risk of mental health problems among adult women who have a single, legal, first-trimester abortion of an unwanted pregnancy is no greater than the risk among women who deliver an unwanted pregnancy. Evidence did not support the claim that observed associations between abortion and mental health problems are caused by abortion per se as opposed to other preexisting and co-occurring risk factors. Most adult women who terminate a pregnancy do not experience mental health problems. Some women do, however. It is important that womens varied experiences of abortion be recognized, validated, and understood.

Hypertension affects neurobehavioral functioning

&NA; This study compared the neurobehavioral performance of hypertensive and normotensive men and women using neuropsychological, information‐processing, and psychometric assessments. One hundred subjects, including 68 hypertensive and 32 normotensive individuals, completed a test battery that yielded scores on measures of speed of information processing, verbal and figural memory, psychosocial functioning, Type A behavior, and locus of control. Results showed that, compared with the normotensive individuals, the hypertensives performed more poorly on a set of tasks that measure speed of information processing and short‐term memory (Digit Symbol, Digit Span (Backwards), and Reaction Time (slope)). The hypertensives also reported higher levels of state anxiety relative to their normotensive counterparts. The effects of hypertension on neurobehavioral functioning could not be accounted for on the basis of age or education.

Processing of Grammatical Gender in Normal and Aphasic Speakers of Russian

Sensitivity to grammatical gender was investigated in 22 Russian-speaking aphasic patients, compared with young controls. Experiment 1 used a cued shadowing paradigm to assess gender priming (facilitation and/or inhibition of lexical access by a prenominal modifier with congruent, incongruent or neutral gender). Experiment 2 used a grammaticality judgment paradigm with similar stimuli. Normals showed significant interactions between gender and priming in Experiment 1 (facilitation for feminine and neuter nouns but not for masculines) and Experiment 2 (larger effects of context on feminine and neuter nouns) that we interpret as a Markedness Effect. Patients showed significant priming in Experiment 1 and above-chance accuracy in Experiment 2, but failed to show reduced effects for the least-marked masculine gender (the Markedness Effect) in either experiment. Context effects were not related to specific aphasic symptoms or subtypes in either experiment. However, canonical correlation revealed differential effects of specific aphasic symptoms on judgment accuracy (false alarms vs. misses). We conclude that knowledge of grammatical gender is spared in Russian aphasics, but gender processing is deviant. A possible model to account for these differences is discussed.

Magnitude of Discrepancy and the Distribution of Attention in Infants.

MCCALL, ROBERT B.; KENNEDY, CINDY BELLOWS; and APPELBAUM, MARK I. Magnitude of Discrepancy and the Distribution of Attention in Infants. CHILD DEVELOPMENT, 1977, 48, 772-785. This paper reports 2 attempts to demonstrate the discrepancy hypothesis prediction that visual fixation time for human infants should be an inverted-U function of the magnitude of discrepancy between a new stimulus and a familiar standard. Moreover, the inverted-U curve should be less inflected when the discrepancies are accompanied by increases rather than decreases in stimulus information. The experimental design and method of analysis permitted the separation of effects for the familiar stimulus, the new stimulus, and the magnitude of discrepancy, and generalizations for the discrepancy effect across different specific stimulus pairs were possible. The data were in perfect accord with discrepancy hypothesis predictions. These findings were integrated with previous studies of discrepancy. While any single study may possess certain ambiguities, the authors contend that, despite large differences between studies in stimuli, procedure, and analysis, 25 independent groups of infants have displayed the inverted-U discrepancy curve-a convergence of results that make the discrepancy hypothesis a plausible notion.

Effects of early focal brain injury on memory for visuospatial patterns: selective deficits of global-local processing.

Selective deficits in visuospatial processing are present early in development among children with perinatal focal brain lesions (PL). Children with right hemisphere PL (RPL) are impaired in configural processing, while children with left hemisphere PL (LPL) are impaired in featural processing. Deficits associated with LPL are less pervasive than those observed with RPL, but this difference may reflect the structure of the tasks used for assessment. Many of the tasks used to date may place greater demands on configural processing, thus highlighting this deficit in the RPL group. This study employed a task designed to place comparable demands on configural and featural processing, providing the opportunity to obtain within-task evidence of differential deficit. Sixty-two 5- to 14-year-old children (19 RPL, 19 LPL, and 24 matched controls) reproduced from memory a series of hierarchical forms (large forms composed of small forms). Global- and local-level reproduction accuracy was scored. Controls were equally accurate on global- and local-level reproduction. Children with RPL were selectively impaired on global accuracy, and children with LPL on local accuracy, thus documenting a double dissociation in global-local processing.

Later language development in narratives in children with perinatal stroke

Studies of young children with unilateral perinatal stroke (PS) have confirmed the plasticity of the developing brain for acquiring language. While recent studies of typically developing children have demonstrated the significant development of language well into adolescence, we know little regarding the course of language development in the PS group as they mature. Will children with PS continue to show the same remarkable plasticity that they exhibited at younger ages? In the present paper we investigate later language and discourse in children with perinatal stroke (ages 7-16) using spoken personal narrative as the discourse context. In contrast to the findings of the discourse studies of younger children with PS, children with left hemisphere lesions made more morphological errors, used less complex syntax and fewer syntactic types than controls; they also produced more impoverished story settings. In contrast, those with right hemisphere lesions performed comparably to controls, except in their impoverished use of complex syntax. The findings provide insight into the nature of later spoken language development in these children, revealing both the nature and extent of neuroplasticity for language as well as potential regional biases.

Quantifying Dissociations in Neuropsychological Research

Double dissociations play an important role in neuropsychology, but they are often identified through subjective estimates of “high” versus “low” performance, without considering the probability that such an outcome might have occurred by chance. To determine whether two measures “come apart” in an interesting way in brain-damaged patients, it is important to know the degree to which variance in one measure can be predicted by variance in the other. This study introduces a statistical procedure to determine the probability of a double dissociation when the correlation between measures is taken into account. Different quantitative definitions of dissociations were compared in two large samples of neurological patients, and applied to four pairs of measures (two for language, two for hemispatial neglect) with different degrees of intercorrelation (ranging from +.21 to +.84). If the correlation between measures is not taken into account, large numbers of dissociated cases may be missed, especially for measures that are highly correlated. There are also qualitative differences between methods in the identity of those individuals who meet each definition.

Journal article reporting standards for quantitative research in psychology: The APA publications and Communications Board task force report

Following a review of extant reporting standards for scientific publication, and reviewing 10 years of experience since publication of the first set of reporting standards by the American Psychological Association (APA; APA Publications and Communications Board Working Group on Journal Article Reporting Standards, 2008), the APA Working Group on Quantitative Research Reporting Standards recommended some modifications to the original standards. Examples of modifications include division of hypotheses, analyses, and conclusions into 3 groupings (primary, secondary, and exploratory) and some changes to the section on meta-analysis. Several new modules are included that report standards for observational studies, clinical trials, longitudinal studies, replication studies, and N-of-1 studies. In addition, standards for analytic methods with unique characteristics and output (structural equation modeling and Bayesian analysis) are included. These proposals were accepted by the Publications and Communications Board of APA and supersede the standards included in the 6th edition of the Publication Manual of the American Psychological Association (APA, 2010).

Development of autonomy: role of walking onset and its timing.

The observations of psychoanalytically oriented clinicians such as Mahler, Pine, and Bergman and Greenacre were descriptive of intriguing aspects of the infants transition to upright locomotion. Yet, research on how walking creates changes in the infant and in the family have scarcely been studied. In this naturalistic home study, 46 infants were designated “earlier” (13 girls and 10 boys) and “later” (12 girls and 11 boys) walkers based on their relative timing of entry into this developmental transition. Analyses between these two groups were done with age held constant and indicated that the earlier walkers showed a greater rise in autonomous functioning across the transition to self-produced, upright locomotion. Autonomy was assessed as infant proximity-seeking and distancing with respect to mother and “testing of wills” between mother and child. These findings suggested that the timing of beginning to walk crucially affects the development of autonomy. In addition to these clear differences associated with the walking transition, there were differences between the two groups in an aspect of temperament, Distress to Limitations, even prior to walking onset as well as at all time points of measurement.
