Sensory judgments improve with practice. Such perceptual learning is often thought to reflect an increase in perceptual sensitivity. However, it may also represent a decrease in response bias, with unpracticed observers acting in part on a priori hunches rather than sensory evidence. To examine whether this is the case, 55 observers practiced…

There is now abundant evidence that human learning and memory are governed by multiple systems. As a result, research is now turning to the next question of how these putative systems interact. For instance, how is overall control of behavior coordinated, and does learning occur independently within systems regardless of what system is in control?…

Autism is currently one of the most prominent and widely discussed human conditions. Its increased prevalence has intensified the demand for effective educational and therapeutic services, and intervention science is providing mounting evidence about practices that positively impact outcomes. The purpose of this report is to describe a set of…

A report is presented which relates to a general hypothesis suggested by previous data on visual response to faces that in the first weeks of life infants develop expectations regarding the human face. Three predictions were made: (1) Silent human faces would elicit less direct regard than faces accompanied by voices; (2) A familiar face would…

Tests infants' dual-process performance (a process mediating response decrements called habituation and a state-dependent process mediating response increments called sensitization) on visual habituation-dishabituation tasks. (HOD)

Two experiments were conducted to investigate the perceptual processes involved in haptic exploration of randomly generated shapes. Experiment one required subjects to detect symmetrical or asymmetrical characteristics of individually presented plastic shapes, also varying in complexity. Scanning time for both symmetrical and asymmetrical shapes…

Adequate improvement of education depends to some extent upon understanding behavior and learning within a social context. (JD)

A child whose behavior reflects only perception of a stimulus and reaction to it is considered more perceptually bound than an adult whose behavior is also directed by theories, values, and ideas. Based on this analysis three testable hypotheses emrege: (1) stimulus complexity is a better predictor of attention for the more perceptually bound, (2)…

This manual is designed to help Army training personnel select and implement a specific approach to achieving specific training goals. Following a general learning model, general training principles are summarized. The rest of the manual shows how specific learning principles are associated with groups of learner performances. Training goals…

The goals of the education of young children and how these goals may best be met are presented. The main thesis of this book is that "the main work of the school is the fostering and developing of mental life, enabling children to experience more fully and consciously all that life has to offer." The book contains 10 chapters. Chapter 1…
