Center-Based Care for Young Children: Examining Predictors of Quality

The authors collected information from caregivers, trained observers, and parents to investigate quality elements in child-care programs designed for young children in center-based settings. Participants were 75 parents of children aged 15 to 36 months and their caregivers from 13 child-care centers in a southeastern state. Observers collected indicators of program quality and process and structural quality indicators, including adult-child ratio, group size, use of planned activities, use of child-designated space, housekeeping activities, and caregiver-child interactions. Participants responded to questions regarding their child-rearing beliefs, social support networks, perceived stress levels, and demographic characteristics. The best predictors of higher quality care and sensitive caregiver-child interaction in centers were specialized caregiver training, higher adult-child ratios, use of planned activities, and less perceived stress by caregivers. Implications of these findings are discussed.     

The Effect of Differential Post-Weaning Environment on the Rigidity of an Animal's Behavior

Seventy-two first, second and third grade boys and girls were administered seriation problems involving different combinations of shape and color variation. Success rates and latency scores were influenced by shape variation, but not by color variation or grade level. The failure to obtain predicted interactions between the effects of grade level and stimulus variation was attributed to the clarity of the relevant stimulus dimension.     

An Informational Analysis of Active Kinesthesis as Measured by Amplitude of Movement

5 blindfolded Ss were required to make absolute judgments of the extent to which their extended right arm was voluntarily moved in the horizontal plane. The first experiment entailed the judgment of 20 different amplitudes and from these data a scale of equal discriminability was constructed for each S. From these individual scales amplitudes were selected for 5 additional absolute judgment experiments where the number of amplitudes were varied from 4 to 16. Analysis of the mean equal discriminability scale showed that kinesthetic sensitivity varied over the continuum of movements. The primary analysis of information transfer between number of amplitudes of movement and responses indicated that information transfer varied considerably over the 5 experiments with a maximum transfer of 2.48 bits occurring when 16 amplitudes were used. These results were discussed in terms of the possible cues involved in movement discrimination and whether kinesthetic cues could be used in a closed-loop model of voluntary movement control.     

Psychophysics of Kinesthesis

A horizontal straight-arm movement was used to determine the relationship between the physical stimulus continuum and the psychological continuum of kinesthetic extent of arm movement. A power function with an exponent of 1.075 best described this relationship. In addition, to classify extent of movement as belonging to either a prothetic or metathetic continuum, the category scale was derived. According to the functional criteria described by Stevens (1957), extent of movement was subserved by a metathetic process which would indicate that, for the present task, judgments were made through the use of positional cues rather than amplitude cues.     

Retention Characteristics of Motor Short-Term Memory Cues

The retention characteristics of several cues thought to underlie movement reproduction ability were examined and the results were discussed in terms of two models of motor short-term memory (Laabs, 1973; Pepper & Herman, 1970). Trace decay was indexed by constant error and not variable error. It appeared that the movement cues studied all had access to the central processing capacity in that forgetting did not occur until rehearsal was blocked by the introduction of a secondary task. However, there was some evidence to indicate that different cues are centrally represented in varying degrees of exactness. In this respect reliance on active movement cues and location cues produced better reproduction than passive movement and distance cues, respectively. The existence of an adaptation level established from the range of movement utilized was supported, and short movements were more dependent on central processing capacity than were long movements.     

Rorschach Responses in Healthy,Community Dwelling Older Adults

Five predicted relationships between age and intellectual level and 16 Rorschach variables were examined through a cross-sectional analysis of 47 healthy, community-dwelling elderly men and women. Subjects were compared by age and intellectual level using gender, level of medication, and scores on the Geriatric Depression Scale (GDS) and the Geriatric Social Readjustment Questionnaire (GSRQ) as covariates. Screening tests for psychiatric and physical illness, recent life events, and hearing and vision loss were administered, In contrast to prior research suggesting changes in Rorschach scores with differences in age and intellectual level, only one significant difference was found for these variables. The data suggest that age and intellectual level may contribute less to Rorschach responses than was previously thought.     

Assessing Normal and Abnormal Personality Functioning: Strengths and Weaknesses of Self-Report,Observer, and Performance-Based Methods

Three clinical psychologists were asked to rate the MAPS figures in terms of how much social withdrawal from people the usage of the type of figure would represent if it were used on the test. Their mean ratings were compared with the actual MAPS test performances of normal and schizophrenic patients. The data indicated that, although, psychologists could reliably rate the amount of social withdrawal associated with the figure types, there was no difference in social withdrawal scores between normals and schizophrenics.     

Assessing Interpersonal Aspects of Schizoid Personality Disorder: Preliminary Validation Studies

In 2 studies, we examined the reliability and validity of an interpersonal measure of schizoid personality disorder (SZPD) based on nonverbal behaviors and interpersonal interactions occurring during interviews. A total of 556 male jail inmates in the United States participated in Study 1; 175 mentally disordered offenders in maximum security hospitals in the United Kingdom participated in Study 2. Across both samples, scores on the Interpersonal Measure of Schizoid Personality Disorder (IM–SZ) exhibited adequate reliability and patterns of correlations with other measures consistent with expectations. The scale displayed patterns of relatively specific correlations with interview and self-report measures of SZPD. In addition, the IM–SZ correlated in an expected manner with features of psychopathy and antisocial personality and with independent ratings of interpersonal behavior. We address implications for assessment of personality disorder.
