Interactive simulations are entering mainstream science education. Their effects on cognition and learning are often framed by the legacy of information processing, which emphasized amodal problem solving and conceptual organization. In contrast, this paper reviews simulations from the vantage of research on perception and spatial learning,…

Endophenotypes is one emerging strategy in schizophrenia research that is being used to identify the functional importance of genetically transmitted, brain-based deficits present in this disease. Currently, event-related potentials (ERPs) are timely used in this search. Several ERPs, including N400, present deficits in relation to schizophrenia.…

Five experiments assessed associative symmetry in pigeons. In Experiments 1A, 1B and 2, pigeons learned two-alternative symbolic matching with identical sample- and comparison-response requirements and with matching stimuli appearing in all possible locations. Despite controlling for the nature of the functional stimuli and insuring all requisite…

In this study the effect of a stimulus-stimulus pairing procedure was used as part of a clinical investigation to increase vocalizations for two young children diagnosed with autism. This procedure involved pairing a vocal sound with a preferred stimulus (e.g., toy) to condition automatic reinforcement. In addition, this study assessed the effects…

Aphasia is an acquired language impairment that affects over 1 million individuals, the majority of whom are over age 65 (Groher, 1989). This disorder has typically been conceptualized within a cognitive neuroscience framework, but a behavioral interpretation of aphasia is also possible. Skinner's (1957) analysis of verbal behavior proposes a…

In two experiments, we examined whether 14-month-olds understand the subjective nature of gaze. In the first experiment, infants first observed an experimenter express happiness as she looked inside a container that either contained a toy (reliable looker condition) or was empty (unreliable looker condition). Then, infants had to follow the same…

The attentional blink paradigm was used to examine whether emotional stimuli always capture attention. The processing requirement for emotional stimuli in a rapid sequential visual presentation stream was manipulated to investigate the circumstances under which emotional distractors capture attention, as reflected in an enhanced attentional blink…

This study investigated the mental representation of music notation. Notational audiation is the ability to internally "hear" the music one is reading before physically hearing it performed on an instrument. In earlier studies, the authors claimed that this process engages music imagery contingent on subvocal silent singing. This study refines the…

Thirty years of work as a graphic facilitator listening visually to people in every kind of organization has convinced the author that visual intelligence is a key to navigating an information economy rich with multimedia. He also believes that theory and disciplines developed by practitioners in this new field hold special promise for educators…

The touchscreen testing method for rodents is a computer-automated behavioral testing method that allows computer graphic stimuli to be presented to rodents and the rodents to respond to the computer screen via a nose-poke directly to the stimulus. The advantages of this method are numerous; however, a systematic study of the parameters that…

It was hypothesized that male perpetrators of domestic violence in the early stages of a 1-year process of cognitive restructuring therapy would manifest on the Rosenzweig Picture-Frustration Study higher levels of extra-aggressiveness than in later stages of the therapy process. A sample of male batterers in the process of treatment took the…

How the type of representation (icons, photos of objects in context, photos of objects in isolation) displayed on a hand-held computer affected recognition performance in young adults with cognitive disabilities was examined. Participants were required to match an object displayed on the computer to one of three pictures projected onto a screen.…

A key area of weakness in individuals with fetal alcohol spectrum disorder (FASD) is working memory, thus the goal of this study was to determine whether teaching children (aged 4-11) with FASD verbal rehearsal would increase their memory. Rehearsal training has been effective in other populations with working memory difficulties, so we…

How rapidly does boundary extension occur? Across experiments, trials included a 3-scene sequence (325 ms/picture), masked interval, and repetition of 1 scene. The repetition was the same view or differed (more close-up or wide angle). Observers rated the repetition as same as, closer than, or more wide angle than the original view on a 5-point…

Previous studies have shown that most individuals with autism do not show empathic responding. The present study is an attempt to teach such skills. Script-fading procedures have been used to teach other social-interaction skills, so they are applied here to teach empathic responding. This study included three adolescents with autism, two males…
