The Impact Of Category Separation On Unsupervised Categorization, Shawn W. Ell, Gregoryh F. Ashby
The Impact Of Category Separation On Unsupervised Categorization, Shawn W. Ell, Gregoryh F. Ashby
Psychology Faculty Scholarship
Most previous research on unsupervised categorization has used unconstrained tasks in which no instructions are provided about the underlying category structure or the stimuli are not clustered into categories. Few studies have investigated constrained tasks in which the goal is to learn pre-defined stimulus clusters in the absence of feedback. These studies have generally reported good performance when the stimulus clusters could be separated by a one-dimensional rule. The present study investigated the limits of this ability. Results suggest that even when two stimulus clusters are as widely separated as in previous studies, performance is poor if within-category variance on …
The Relationship Between Performance In Near Match-To-Sample Tasks And Fluid Intelligence., Meredith C. Frey
The Relationship Between Performance In Near Match-To-Sample Tasks And Fluid Intelligence., Meredith C. Frey
Psychology Faculty Scholarship
Match-to-sample is a timed task in which a subject is presented with a visual stimulus (the probe) and must select a match to that stimulus (the target) from among an array of distractors. These tasks are frequently employed as tests of basic cognitive abilities and demonstrate consistent correlations with measures of intelligence. In the current study, a match-to-sample task was modified to produce near-match conditions (trials for which no exact match existed). Two factors were manipulated: type of discrepancy between the target and probe (additive or subtractive) and degree of discrepancy between target and probe (1 element or 2 elements). …
Peer Acceptance And Friendship As Predictors Of Early Adolescents' Adjustment Across The Middle School Transition, Julie Newman Kingery, Cynthia A. Erdley, Katherine C. Marshall
Peer Acceptance And Friendship As Predictors Of Early Adolescents' Adjustment Across The Middle School Transition, Julie Newman Kingery, Cynthia A. Erdley, Katherine C. Marshall
Psychology Faculty Scholarship
This study examines several aspects of adolescents' pretransition peer relationships as predictors of their adjustment to middle school. Participants were 365 students (175 boys; 99% Caucasian) involved in the Time 1 (the spring of fifth grade) and Time 2 (the fall of sixth grade) assessments. Adolescents completed measures that assessed peer acceptance, number of friends, the quality of a specific mutual friendship, loneliness, depression, self-esteem, and involvement in school. Academic achievement and absentee data were obtained from student files. Regression analyses indicated that the pretransition peer variables predicted posttransition loneliness, self-esteem, school involvement, and academic achievement. The patterns of prediction …
The Effects Of Revictimization On Coping And Depression In Female Sexual Assault Victims, Cynthia J. Najdowski, Sarah E. Ullman
The Effects Of Revictimization On Coping And Depression In Female Sexual Assault Victims, Cynthia J. Najdowski, Sarah E. Ullman
Psychology Faculty Scholarship
To examine the effects of being revictimized, 555 women completed 2 mail surveys 1 year apart, reporting their experiences of sexual assault, the strategies they used to cope with those experiences, and feelings of depression. Path analyses, controlling for baseline coping and depression, revealed that those who were revictimized during the study reported using more maladaptive and adaptive coping strategies than did those who were not revictimized (β = .11 and β = .16, respectively). Further, women who were revictimized reported more depression than others (β = .15). This effect was explained in part by revictimized women's increased maladaptive coping. …
Prospective Changes In Attributions Of Self-Blame And Social Reactions To Women’S Disclosures Of Adult Sexual Assault, Cynthia J. Najdowski, Sarah E. Ullman
Prospective Changes In Attributions Of Self-Blame And Social Reactions To Women’S Disclosures Of Adult Sexual Assault, Cynthia J. Najdowski, Sarah E. Ullman
Psychology Faculty Scholarship
The present longitudinal study examined relations between self-blame attributions and social reactions to disclosure in a community sample of adult sexual assault victims (N = 555). Cross-lagged panel analyses showed that neither characterological self-blame nor behavioral self-blame related to negative social reactions over the 1-year follow-up period. In contrast, characterological but not behavioral self-blame predicted fewer positive reactions over time. Although positive reactions did not reduce self-blame, negative reactions led to greater characterological, but not behavioral, self-blame during the course of the study. Thus, relations between self-blame and social reactions were not reciprocal but rather quite complex. The effects …
The Experience Of Mental Health Service Use For African American Mothers And Youth, Richard Thompson, Barbara L. Dancy, Tisha R. A. Wiley, Sylvia P. Perry, Cynthia J. Najdowski
The Experience Of Mental Health Service Use For African American Mothers And Youth, Richard Thompson, Barbara L. Dancy, Tisha R. A. Wiley, Sylvia P. Perry, Cynthia J. Najdowski
Psychology Faculty Scholarship
Little is known about African American families’ experiences with mental health services. A purposive sample of 40 dyads of African American youth (aged 13 to 19) and their mothers participated in a cross-sectional qualitative research design using semi-structured interviews that elicited information about their past experiences and satisfaction with mental health services. Though rarely received, group and family therapy were perceived favorably. However, both mothers and youth reported dissatisfaction centered on medication and lack of professionalism, confidentiality, and concern by providers. The failure of mental health services providers to meet basic standards of quality and professionalism may explain the low …
Vulnerability And Protective Factors For Sexual Assault, Sarah E. Ullman, Cynthia J. Najdowski
Vulnerability And Protective Factors For Sexual Assault, Sarah E. Ullman, Cynthia J. Najdowski
Psychology Faculty Scholarship
Approximately 1 in 5 women experience sexual assaults in adulthood during their lives (see Post, this volume, for review), including experiences of unwanted sexual contact, sexual coercion, attempted rape, and completed rape that result from threat, force, or incapacitation from alcohol or drugs (either willingly or unwillingly consumed).
