Cognitive Diagnosis for Small Educational Programs: The General Nonparametric Classification Method

The focus of cognitive diagnosis (CD) is on evaluating an examinee’s strengths and weaknesses in terms of cognitive skills learned and skills that need study. Current methods for fitting CD models (CDMs) work well for large-scale assessments, where the data of hundreds or thousands of examinees are available. However, the development of CD-based assessment tools that can be used in small-scale test settings, say, for monitoring the instruction and learning process at the classroom level has not kept up with the rapid pace at which research and development proceeded for large-scale assessments. The main reason is that the sample sizes of the small-scale test settings are simply too small to guarantee the reliable estimation of item parameters and examinees’ proficiency class membership. In this article, a general nonparametric classification (GNPC) method that allows for assigning examinees to the correct proficiency classes with a high rate when sample sizes are at the classroom level is proposed as an extension of the nonparametric classification (NPC) method (Chiu and Douglas in J Classif 30:225–250, 2013). The proposed method remedies the shortcomings of the NPC method and can accommodate any CDM. The theoretical justification and the empirical studies are presented based on the saturated general CDMs, supporting the legitimacy of using the GNPC method with any CDM. The results from the simulation studies and real data analysis show that the GNPC method outperforms the general CDMs when samples are small.     

Relationships among burnout, job involvement, and organizational citizenship behavior

R. Cropanzano, D. E. Rupp, and Z. S. Byrne (2003) found that emotional exhaustion (i.e., 1 dimension of burnout) negatively affects organizational citizenship behavior (OCB). The authors extended this research by investigating relationships among 3 dimensions of burnout (emotional exhaustion, depersonalization, and diminished personal accomplishment) and OCB. They also affirmed the mediating effect of job involvement on these relationships. Data were collected from 296 paired samples of service employees and their supervisors from 12 hotels and restaurants in Taiwan. Findings demonstrated that emotional exhaustion and diminished personal accomplishment were related negatively to OCB, whereas depersonalization had no independent effect on OCB. Job involvement mediated the relationships among emotional exhaustion, diminished personal accomplishment, and OCB.     

Sex-Dimorphic Color Preference in Children with Gender Identity Disorder: A Comparison to Clinical and Community Controls

The present study was designed to assess sex-dimorphic color preferences in children with gender identity disorder (47 boys, 18 girls), clinical controls (65 boys, 35 girls), and community controls (65 boys, 35 girls). The mean age of the children was 7.63 years (range?=?3–12 years). Children were shown a hexagon-shaped display of 144 colors extracted from PowerPoint?. Each child was asked to choose his or her three favorite colors (Trials 1–3) by pointing to them, naming them, and then to provide a justification for each choice. From the entire array, children labeled a total of 11 different colors: black, blue, brown, gray, green, orange, pink, purple, red, white, and yellow. For three of the colors (blue, pink/purple, and red), there was evidence for normative sex differences in color preference, and, for the colors blue and pink/purple, the gender-referred children showed inverted patterns of color preference. For the color blue, luminance values showed that the gender-referred boys and control girls preferred lighter shades, whereas the gender-referred girls and control boys preferred darker shades. Qualitative analysis indicated that gender-specific justifications were uncommon, even for the sex-dimorphic colors. Gender-referred children showed inverted gender-stereotyped color preferences, which are likely related to their more general pattern of cross-gender identification. Principles of gender-differentiated development derived from gender-schema theory are used to explain the group differences in color preferences.     

When modesty fails: The social impact of group-effacing attributions following success or failure

This study explored how group members perceived a fellow group member who made either group-serving or group-effacing attributions following success or failure. Forty male undergraduates from the Chinese University co-operated in pairs with a confederate on a demanding group task. After learning that their group's performance had exceeded or failed to meet a standard, the subjects heard their confederate-partner make group-effacing or group-serving attributions. As predicted, subjects evaluated the group-serving partners more highly (p < 0.05). Preference for group-enhancing members was discussed as a pancultural response arising from the interdependence of group members. Given the process of social categorization, group members rise or fall together and are therefore socialized to support their group.     

Group-serving attributions across intergroup contexts: Cultural differences in the explanation of sex-typed behaviours

This research attempted to integrate Tajfel's (1978) social identity theory with self-presentational concerns by exploring attributions about perceived group differences in behaviour. As such, it dealt with group-level rather than individual-level attributions, exploring whether bias in making such verbal attributions varied as a function of the interviewer's group identity and the presence of an ingroup audience. Undergraduate men and women at The Chinese University of Hong Kong rated the appropriateness of ingroup-favouring and outgroup-favouring explanations for male-typed and female-typed behaviors in a face-to-face interview. A group-serving bias was found for female-typed behaviours, but only when the same-sex audience was absent. A conceptual replication of the experiment was run in the United States to examine the possible cultural basis for the Chinese moderation of favouritism in the audience condition. The group-serving bias was more robust for the American undergraduates, extending across male- and female-typed behaviours and also across audience conditions, It was argued that these cultural differences in attributional bias appear to reflect the strength of the movement for women's liberation and norms surrounding the avoidance of conflict in the United States and Hong Kong.     

Three wishes of gifted and nongifted adolescents

Three wishes of 69 gifted and 66 nongifted adolescents within the United States were solicited in a group situation. The findings indicated that personal wishes were of the most concern for both gifted and nongifted adolescents, and that male adolescents in both groups tended to value material possessions more often than did female adolescents. A significant between-groups difference revealed that gifted adolescents expressed more altruistic and fewer goal wishes than their nongifted peers. These kinds of data are one more means of describing, for teachers and counselors, a general picture of students' psychological and social orientations.     

A test of the sensorimotor account of vision and visual perception

Two theories define the relationship between sensory experience and perception of location. The doctrine of specific nerve energies relies on hard-wired, genetically specified relationships between stimulation and perception, modifiable only within limits by adaptation. In a newer sensorimotor account, experience tunes the relationship between stimulation and perception. The perception of pressure phosphenes can differentiate the two theories, because the phosphene appears at a location predicted by physiological optics and in a modality predicted by specific nerve energies. Moving a finger vertically along the outer orbit of the eye while pressing gently on it through the lid during nasally directed gaze results in apparent motion of the phosphene out of phase with the finger, therefore in contradiction to information from motor efference to the finger, tactile sense at the fingertip, eyelid and bulb, joint receptors, and proprioception from muscles driving the finger. A test of the sensorimotor theory giving it every advantage had six observers in darkness moving their fingers along the eye and observing phosphenes for 1 h and 2400 motion cycles; the phosphene always obeyed the doctrine of specific nerve energies, never adapting or changing modality as the sensorimotor theory predicts.     

Display polarity, stimulus exposure duration, and visual lobe shape

This study investigated the effects of visual display polarity and stimulus exposure duration on visual lobe shape. Analysis showed that regardless of display polarity and exposure duration combinations tested here, visual lobe contours were slightly irregular and asymmetric, of medium roundness, with a moderately rough boundary, and horizontally elongated with a mean length-width ratio of 1.53. Visual lobes mapped with negative display polarity were significantly rounder, slightly more regular and more symmetric along the vertical axis, compared with those mapped with positive polarity. Under the different polarity conditions, there were no significant differences in visual lobe area, perimeter, boundary smoothness, and elongation. When stimulus exposure duration increased from 200 to 400 msec. and from 200 to 300 msec., there were significant increases in the visual lobe area, perimeter, roundness, boundary smoothness, and regularity. No such changes were found when duration increased from 300 to 400 msec. Exposure durations did not have a significant effect on the shape categories of elongation and horizontal symmetry for the different stimuli. There were no statistically significant interactions between polarity and stimulus exposure duration for any of the lobe shape indexes used here.     

Perceived Conflict Styles of Adult Children and their Parents: What Is the Connection?

The purpose of this study was to explore the potential genesis of conflict styles for couples by evaluating the association between parents’ conflict styles and those of their adult children and their adult children’s partners. Using Social Learning Theory as a theoretical foundation, the four conflict typologies from Gottman’s work (avoidant, validating, volatile, and hostile) were applied to study the participants’ conflict styles. Multinomial logistic regression was then conducted on a sample of 25,511 participants, testing the relationships between the conflict styles of parents, their adult children’s conflict styles, and their adult children’s partners’ conflict styles. All of the perceived parental conflict styles were linked to the same conflict styles in adult children. However, for adult children and their partners, the patterns were mixed. Whereas having validating parents predicted having validating partners, having avoidant or hostile parents predicted having hostile partners. The results suggest the possibility of the intergenerational transmission of conflict styles between parents and their adult children as well as contributing to the established research on assortative mating in that individuals may be more likely to select partners who are similar to them in terms of their approaches to conflict. The results of this study have important implications for intervening early in families with less functional conflict styles.
