From implicit skills to explicit knowledge: a bottom-up model of skill learning

This paper presents a skill learning model CLARION. Different from existing models of mostly high-level skill learning that use a top-down approach (that is, turning declarative knowledge into procedural knowledge through practice), we adopt a bottom-up approach toward low-level skill learning, where procedural knowledge develops first and declarative knowledge develops later. Our model is formed by integrating connectionist, reinforcement, and symbolic learning methods to perform on-line reactive learning. It adopts a two-level dual-representation framework (Sun, 1995), with a combination of localist and distributed representation. We compare the model with human data in a minefield navigation task, demonstrating some match between the model and human data in several respects.     

Application of social identity theory in group therapy with stigmatized adults.

Social identity theory was applied in group therapy for adults with mild mental retardation. Social identity theory suggests that social group membership, also called collective identity, has an impact on self-esteem. Individuals will try to maintain self-esteem by viewing their social groups positively. This may not be possible for individuals who are members of a stigmatized group. However, it may be possible to enhance self-esteem by broadening one's awareness of collective identity. Furthermore, being able to positively view other individuals who are co-members of one's own stigmatized group can also have positive consequences for self-esteem. A clinical vignette demonstrates this process in group therapy. Results are discussed as being applicable to members of various stigmatized groups.     

Factors Associated with Perceived Paternal Involvement in Childrearing

Interest in paternal involvement in child care has increased as the demands on the time and resources of maternal caretakers have increased. The purpose of the present study was to examine variables associated with perceived paternal involvement in child care. Participants were 137 (90 European American and 47 African American) fathers of children between the ages of 2 and 6. Hierarchical multiple regression and analyses of variance indicated that ethnicity, gender role orientation, and perceived skill at child care were associated with higher levels of perceived paternal engagement in and responsibility for child care. Partners' work status was associated with perceived paternal responsibility for, but not engagement in child care. Data suggest that fathers' perceptions of their abilities, gender role, and family requirements may combine to influence child care involvement.     

“Statistical,” “Practical,” and “Clinical”: How Many Kinds of Significance Do Counselors Need to Consider?

The present article reviews and distinguishes 3 related but different types of significance: “statistical,” “practical,” and “clinical.” A framework for conceptualizing the many “practical” effect size indices is described. Several effect size indices that counseling researchers can use, or that counselors reading the literature may encounter, are summarized. A way of estimating “corrected” intervention effects is proposed. It is suggested that readers should expect authors to report indices of “practical” or “clinical” significance, or both, within their research reports; and it is noted that indeed some journals now require such reports.     

The role of social supports in the bereavement process of surviving spouses of suicide and natural deaths.

This report examines the changing role of social supports in the bereavement of spouses of elderly suicide and natural deaths, focusing on differences and similarities in relation to gender, time, and mode of death. Measurements were obtained 4 times after death (within 2 months, at 6 months, at 12 months, and at 2 to 2 1/2 years) on 79% of the 108 survivors of elderly suicide, 89% of the 199 natural death survivors, and 79% of the nonbereaved controls. The results indicated that the suicide survivors received significantly less emotional support for their feelings of depression and grief than the natural death survivors, and that they did not confide in the persons in their network any more than the nonbereaved controls did. Women report receiving more support overall than men. A low spot in social supports occurred at the 6-month point after loss for both bereaved groups, but primarily in practical help received by natural death survivors. By the end of the second year, both practical and emotional supports had increased to at least the same level as immediately after death.     

Confirmation in Couples' Communication About Weight Management: An Analysis of How Both Partners Contribute to Individuals' Health Behaviors and Conversational Outcomes

Using confirmation theory, this study investigated how romantic couples' (N = 100) accepting and challenging communication was associated with several weight management (WM) outcomes (i.e., partners' general effectiveness in motivating each other to enact healthy behaviors, productivity of WM conversations, and diet and exercise behaviors). Actor–partner interdependence model analyses showed that acceptance and challenge from partners simultaneously predicted how effective partners were in motivating healthy behaviors, but these components of confirmation predicted the other outcomes in different ways. Analyses across the outcomes also revealed that similar partner communication styles predicted general effectiveness, more productive WM conversations, and healthier eating habits. The findings of this study highlight the importance of assessing the interdependence of partners' WM efforts.     

Priming of face matching in amnesia.

Priming was studied in a task that required a speeded response to photographs of faces. On each trial, subjects viewed two faces and decided if the same person was shown twice or if two different people were shown. Both familiar and unfamiliar (i.e., well-known and unknown) faces were used, and some face pairs were repeated with a mean delay of about 10 min. Repetition was associated with faster reaction times in young subjects (Experiment 1) as well as in amnesic patients and age-matched control subjects (Experiment 2). The patients' reaction times were slower overall, although the magnitude of the priming effect did not differ from that in the control subjects. This preservation of a normal reaction-time facilitation in subjects with impaired recognition memory for faces occurred for both familiar and unfamiliar faces, suggesting that amnesia does not necessarily interfere with the acquisition of new information as indexed by this priming effect.
