Multilevel modeling allows for the simultaneous analysis of data gathered at more than 1 unit of analysis (e.g., children nested in schools). It is often used to examine the effects of various contexts on individual differences in change. This paper promotes the application of multilevel models to longitudinal dyadic data in family research. By…

The polysialylated neural cell adhesion molecule (PSA-NCAM) has been implicated in activity-dependent synaptic remodeling and memory formation. Here, we questioned whether training-induced modulation of PSA-NCAM expression might be related to individual differences in spatial learning abilities. At 12 h posttraining, immunohistochemical analyses…

This paper, based on naturalistic data, describes the acquisitional course and use of the articles "a" and "the" in young English-speaking children (18-61 months), with special emphasis on the role of individual variation. A growth modeling approach to the data reveals that children's individual acquisition schedules are similar in trend, but vary…

Analyzed 104 language samples obtained from 42 different normal language learning children at 15, 19, and 35 months of age for the proportional use of 11 grammatical morphemes. Wide variability was found among the samples in the proportional use of each morpheme. (49 references) (JL)

This volume examines the ramifications of individual differences in therapy outcomes for a wide variety of communication disorders. In an era where evidence-based practice is the clinical profession's watchword, each chapter attacks this highly relevant issue from a somewhat different perspective. In some areas of communication disorders,…

We are delighted to welcome you to the International Psychological Applications Conference and Trends 2014, taking place in Porto, Portugal, from 4 to 6 of April. Psychology, in our time, offers a large range of scientific fields where it can be applied. The goal of understanding individuals and groups (mental functions and behavioral…

People can use a variety of different strategies to perform tasks and these strategies all have two characteristics in common. First, they can be evaluated in comparison with either an absolute or a relative standard. Second, they can be used at varying levels of consistency. In the present article, the authors develop a general theory of task…

The "APA Educational Psychology Handbook" reflects the broad nature of the field today, with state-of-the-science reviews of the diverse critical theories driving research and practice; in-depth investigation of the range of individual differences and cultural/contextual factors that affect student achievement, motivation, and beliefs;…

This study examines how teachers actually cope with behavioural problems of included students. In order to understand the impact of individual differences on teachers' coping strategies, the authors looked at the relationship between these strategies and teachers' democratic beliefs and self-efficacy. Participants were 33 teachers in Israel, who…

Background: We assess individual differences in the caregiving environments of young children being raised in institutions in Romania in relation to developmental characteristics such as physical growth, cognitive development, emotional expression, and problem and competence behaviors. Method: Videotaped observations of the child and favorite…

Females, students of color, and students of low socioeconomic status (SES) are often underserved or marginalized in mathematics education. However, some instructional approaches and intervention programs have been shown to educate these students more equitably. This study examines how girls of diverse racial/ethnic and socioeconomic backgrounds…

Fluctuations in cognitive task performance in older individuals have been reported. To examine intraindividual variability as a function of practice, 34 younger and 34 older female participants, aged 20-30 years and 70-82 years, respectively, performed a reading span task 16 times over four sessions. Each individual's recall accuracy was analyzed…

Performance on a wide variety of memory tasks can be hypothesized to be influenced by processes associated with controlling the contents of memory. In this project 328 adults ranging from 18 to 93 years of age performed six tasks (e.g., multiple trial recall with an interpolated interference list, directed forgetting, proactive interference, and…

The aims of the study were to test the linkages between achievement goals to task performance, as mediated by state anxiety arousal. Performance expectancy was also examined as antecedents of achievement goals. A presentation task in a computer practice class was used as achievement task. Fifty-three undergraduates (37 females and 16 males) were…

Although the veridicality of unconscious perception is increasingly accepted, core issues remain unresolved [Jack, A., & Shallice, T. (2001). Introspective physicalism as an approach to the science of consciousness. "Cognition, 79," 161-196], and sharp disagreement persists regarding fundamental methodological and theoretical issues. The most…
