Validity of the Developmental Test of Visual-Motor Integration Supplemental Developmental Test of Visual Perception

Visual perceptual skills of school-age children are often assessed using the Supplemental Developmental Test of Visual Perception of the Developmental Test of Visual-Motor Integration. The study purpose was to consider the construct validity of this test by evaluating its scalability (interval level measurement), unidimensionality, differential item functioning, and hierarchical ordering of its items. Visual perceptual performance scores from a sample of 356 typically developing children (171 boys and 185 girls ages 5 to 11 years) were used to complete a Rasch analysis of the test. Seven items were discarded for poor fit, while none of the items exhibited differential item functioning by sex. The construct validity, scalability, hierarchical ordering, and lack of differential item functioning requirements were met by the final test version. Since 7 test items did not fit the Rasch analysis specifications, the clinical value of the test is questionable and limited.     

Measurement of equity sensitivity: a comparison of the Equity Sensitivity Instrument and Equity Preference Questionnaire

The psychometric properties of the Equity Sensitivity Instrument (Huseman, Hatfield, & Miles, 1985, 1987) and Equity Preference Questionnaire (Sauley & Bedeian, 2000) are compared. 173 undergraduate business majors completed several work attitude and personality measures. Results suggest that the Equity Preference Questionnaire may be a better measure of the equity sensitivity construct than the Equity Sensitivity Instrument which is typically used in research. Reliabilities for the scores on the Equity Sensitivity Instrument and Equity Preference Questionnaire were equivalent (coefficient alphas of .85 and .86, respectively); however, evidence for convergent and content validity was greater for the Equity Preference Questionnaire. Understanding individual differences in perceptions of equity and how best to measure these differences can affect workplace outcomes (e.g., turnover, employee engagement.     

Six Ways of Salvation: How Does Jesus Save?

Abstract : Using the model method for comparative analysis of theological theories, this article compares and contrasts six models of atonement: (1) Jesus as teacher of true knowledge; (2) Jesus as moral example and influence; (3) Jesus as the victorious champion and liberator; (4) Jesus as our satisfaction; (5) Jesus as the happy exchange; and (6) Jesus as the final scapegoat.     

Who wants to live forever? Immortality,authenticity, and living forever in the present

Death is a bad thing by virtue of its ability to frustrate the subjectively valuable projects that shape our identities and render our lives meaningful. While the presumption that immortality would necessarily result in boredom worse than death proves unwarranted, if the constraint of mortality is a necessary element for virtues, relationships, and motivation to pursue our life-projects, then death might nevertheless be a necessary evil. Mortal or immortal, it’s clear that the value of one’s life depends on its subjectively determined quality, rather than its quantity. Thus, it is imperative to live forever in the present, with flourishing always in mind.     

Does Friendship Matter? An Examination of Social Physique Anxiety in Adolescence1

The role of peer group composition and influence variables on social physique anxiety was examined. Peer network data were gathered on 375 adolescents (181 male, 194 female). Females reported experiencing higher social physique anxiety, more pressure and encouragement to alter their physique from peers, greater body‐related discussion, and greater identification with the peer group than did males. Regression analyses revealed 2 peer influence variables—peer pressure and relative attractiveness of peers—to be significant predictors of social physique anxiety. A third variable—extent to which the individual identified with peer network—was a significant predictor for females. Results are discussed in reference to previous research, and future research directions are identified.     

Eye-blink conditioning is associated with changes in synaptic ultrastructure in the rabbit interpositus nuclei

Eye-blink conditioning involves the pairing of a conditioned stimulus (usually a tone) to an unconditioned stimulus (air puff), and it is well established that an intact cerebellum and interpositus nucleus, in particular, are required for this form of classical conditioning. Changes in synaptic number or structure have long been proposed as a mechanism that may underlie learning and memory, but localizing these changes has been difficult. Thus, the current experiment took advantage of the large amount of research conducted on the neural circuitry that supports eye-blink conditioning by examining synaptic changes in the rabbit interpositus nucleus. Synaptic quantifications included total number of synapses per neuron, numbers of excitatory versus inhibitory synapses, synaptic curvature, synaptic perforations, and the maximum length of the synapses. No overall changes in synaptic number, shape, or perforations were observed. There was, however, a significant increase in the length of excitatory synapses in the conditioned animals. This increase in synaptic length was particularly evident in the concave-shaped synapses. These results, together with previous findings, begin to describe a sequence of synaptic change in the interpositus nuclei following eye-blink conditioning that would appear to begin with structural change and end with an increase in synaptic number.     

Investigating naturalistic decision making in a simulated microworld: What questions should we ask?

Computer-simulated microworlds can provide a controlled method for investigating concepts related to naturalistic decision making (NDM). However, the extent to which these tools can be used to generate meaningful outcomes is unknown. The current study used a microworld called Networked Fire Chief (NFC) to explore the range of skills and knowledge acquired as participants gained practice on the program. The complexity of the NFC NDM environment was also explored. Twenty participants each completed 20 equivalent 5-min scenarios on NFC. Interview data, behavioral data and performance scores were collected across the trials. Results confirmed that NFC provides an environment that promotes appropriate perceptual-cognitive processing for NDM. However, performance improved to only a small extent across the 20 trials in four performance areas: speed, accuracy, efficiency and planning. In addition, the number of personal and situational factors to be considered when decision making on NFC was not comparable with real-world NDM environments. Overall, results indicated that the use of microworlds for research should be regulated by an understanding of the limitations of their applicability.     

Community-Based Interventions to Reduce Low Income, African American Women's Risk of Sexually Transmitted Diseases: A Randomized Controlled Trial of Three Theoretical Models

A community-based sample of disadvantaged African American women (n = 445) was recruited to participate in 1 of 3 theoretically driven experimental interventions based on either the theory of gender and power, social learning theory, or cognitive behavioral theory. Intervention outcomes were compared with a waiting list control condition. From baseline to postintervention, women in the experimental interventions showed differential change on cognitive indices (knowledge and attitudes) and skill acquisition (partner negotiation skills, correct condom application, lubricant selection, and information-provision to social networks) whereas control participants were unchanged. Women in the 3 experimental interventions also completed follow-up assessments for 1 year following the interventions. In all 3 experimental conditions, condom use increased relative to the control group and there were no differences between the experimental interventions. Women who participated in one of the theoretically grounded interventions continued to increase condom use over the following year. Women entering new relationships reported significantly more condom use than did women who remained in ongoing relationships. The findings suggest that intervention models that have proven effective for women who engage in high-risk behavior may be less effective for women in established relationships for whom risk is primarily derived from the extrarelationship behavior of their partners.     

Doesn’t see,doesn’t know: is anticipatory looking really related to understanding or belief?

Clements and Perner (Cognitive Development, 9 (1994), 377–397) reported that children show understanding of a story character’s belief in their anticipatory looking responses before they show this in their answers to test questions. According to Clements and Perner the anticipatory looking responses provide evidence of implicit understanding of belief. This paper examines the possibility that the anticipatory looking measure is indicative of (a) children using a seeing = knowing rule, i.e. children linking not seeing with ignorance rather than a sensitivity to belief, or (b) a tendency to associate the protagonist with the left‐hand container. Thirty‐two children aged between 2 years 11 months and 4 years were told a false belief story similar to that used in Clements and Perner (1994) except that three containers were used instead of two. The protagonist first looks inside the middle box but then puts the object in the left‐hand box. In his absence, a second character moves the object unexpectedly to the right‐hand box. If children’s anticipatory looking was based on sensitivity to belief then they should have looked clearly to the left‐hand box. If it was based on an association bias or sensitivity to the character not knowing then they should have looked equally to the left‐hand and middle boxes. The results were consistent with the former prediction suggesting that children’s anticipatory looking responses may indeed be governed by an implicit sensitivity to belief.
