The prediction of intelligence in preschool children using alternative models to regression

Statistical prediction of an outcome variable using multiple independent variables is a common practice in the social and behavioral sciences. For example, neuropsychologists are sometimes called upon to provide predictions of preinjury cognitive functioning for individuals who have suffered a traumatic brain injury. Typically, these predictions are made using standard multiple linear regression models with several demographic variables (e.g., gender, ethnicity, education level) as predictors. Prior research has shown conflicting evidence regarding the ability of such models to provide accurate predictions of outcome variables such as full-scale intelligence (FSIQ) test scores. The present study had two goals: (1) to demonstrate the utility of a set of alternative prediction methods that have been applied extensively in the natural sciences and business but have not been frequently explored in the social sciences and (2) to develop models that can be used to predict premorbid cognitive functioning in preschool children. Predictions of Stanford–Binet 5 FSIQ scores for preschool-aged children is used to compare the performance of a multiple regression model with several of these alternative methods. Results demonstrate that classification and regression treesprovided more accurate predictions of FSIQ scores than does the more traditional regression approach. Implications of these results are discussed.     

Does Age Moderate the Relation Between Social Negativity and Psychological Distress?: A Meta-Analytic Investigation

Recently, Finch et al. (Journal of Personality, 1999) reported the results of a meta-analysis in which social negativity was demonstrated to be positively related to psychological distress. In the present investigation, we employed meta-analytic techniques to test competing hypotheses as to whether age amplifies or dampens the relation of social negativity and psychological distress. A total of 104 effect sizes (e.g., concurrent correlations between self-report measures of social negativity and psychological distress) from 53 independent samples were extracted from 46 journal articles. Contrary to hypotheses, the relation between social negativity and psychological distress was not significantly different for samples of older (60 + years) and younger (<60 years) adults. An explanation was provided for why the present meta-analysis and previous narrative reviews have resulted in discrepant conclusions about negativity effects.     

Multidimensionality of the Nowicki-Strickland locus of control scale for adults

In order to investigate the dimensionality of the Adult Nowicki-Strickland Locus of Control Scale (ANS-IE), the responses of 120 undergraduate psychology majors were subjected to one principal components factor analysis using Kaiser's varimax criterion, Five meaningful factors emerged which accounted or 80.6% of the total variance. Results were discussed in terms of their similarity to other factor analyses using the children's version of this scale and to a factor analysis of the ANS-IE (chandler & Dugovics, 1977) which used a modified response format.     

Longitudinal effects of hope on depression and anxiety: a latent variable analysis

This study tested the prospective effects of hope on depression and anxiety using a longitudinal design. A sample of 522 college students completed self-report measures of hope, depression, and anxiety at three time points, with 1-month delays between administrations. Structural equation modeling was employed to test two cross-lagged panel models of the reciprocal effects of the Agency and Pathways components of hope on depression and anxiety. Results indicated statistically significant negative effects for the Agency component of hope on later depression but no unique effect of the Pathways component of hope on depression. Likewise, Agency showed a statistically significant negative effect on later anxiety, but again Pathways had no significant influence on anxiety. In both cases, neither depression nor anxiety demonstrated any longitudinal effects on either the Agency or Pathways components of hope. Implications of these findings are discussed, along with potential directions for future research.     

Terror mismanagement: evidence that mortality salience exacerbates attentional bias in social anxiety

Death anxiety is a basic fear underlying a range of psychological conditions, and has been found to increase avoidance in social anxiety. Given that attentional bias is a core feature of social anxiety, the aim of the present study was to examine the impact of mortality salience (MS) on attentional bias in social anxiety. Participants were 36 socially anxious and 37 non-socially anxious individuals, randomly allocated to a MS or control condition. An eye-tracking procedure assessed initial bias towards, and late-stage avoidance of, socially threatening facial expressions. As predicted, socially anxious participants in the MS condition demonstrated significantly more initial bias to social threat than non-socially anxious participants in the MS condition and socially anxious participants in the control condition. However, this effect was not found for late-stage avoidance of social threat. These findings suggest that reminders of death may heighten initial vigilance towards social threat.     

Brief Rorschach Records With Children and Adolescents

In order to determine the frequency with which children and adolescents give brief Rorschach ( R < 14) records and to test the hypothesis that brief records represent a resistance to testing, the psychological evaluations of 439 admissions to an inpatient unit were reviewed. Of the records reviewed, 16.6% were found to contain less than 14 responses. When the complete test protocols of those subjects who provided brief records were compared with those of a matched group, it was found that the group with brief records failed to complete the other parts of the evaluation significantly more often than did those subjects who did not give brief records. There was no significant difference between the two groups on IQ scores or on self-report scores of depression, anxiety, and social desirability. Results are interpreted as supporting Exner's (1988) hypothesis that brief records represent a form of resistance to being tested.     

On behalf of the consequence argument: time, modality, and the nature of free action

The consequence argument for the incompatibility of free action and determinism has long been under attack, but two important objections have only recently emerged: Warfield’s modal fallacy objection and Campbell’s no past objection. In this paper, I explain the significance of these objections and defend the consequence argument against them. First, I present a novel formulation of the argument that withstands their force. Next, I argue for the one controversial claim on which this formulation relies: the trans-temporality thesis. This thesis implies that an agent acts freely only if there is one time at which she is able to perform an action and a distinct time at which she actually performs it. I then point out that determinism, too, is a thesis about trans-temporal relations. I conclude that it is precisely because my formulation of the consequence argument emphasizes trans-temporality that it prevails against the modal fallacy and no past objections.     

Longitudinally Foretelling Drug Use in the Late Twenties: Adolescent Personality and Social-Environmental Antecedents

This research focuses on the interrelation of the parent-child attachment, unconventionality, friends' drug use, and the young adult's use of drugs. Data were collected from participants at 4 points in time: early adolescence, late adolescence, early 20s, and late 20s. Data were collected from mothers at the 3 points in time that corresponded with the first 3 collections of data from their children. Both the youths and their mothers were individually interviewed. The findings indicated that the effect of parent-child mutual attachment was mediated through early adolescent personality attributes of greater responsibility, less rebelliousness, and intolerance of deviance. These non-drug-prone personality and behavioral attitudes, in turn, insulated the young adult from affiliating with drug-using peers, and these attitudes were related to less drug use in the early 20s and ultimately in the late 20s. The results suggest that interventions focused on enhancing parent-child mutual attachment should result in a reduction of the risk factors conducive to drug use during the late 20s. The fact that these findings cover a decade and a half, from early adolescence to the late 20s, underscores the significance of placing drug use in a perspective that includes familial and behavioral aspects.
