Unlike other animals, humans have the unique ability to share and use verbal instructions to prepare for upcoming tasks. Recent research showed that instructions are sufficient for the automatic, reflex-like activation of responses. However, systematic studies into the limits of these automatic effects of task instructions remain relatively…

The goal of the present study was to examine if and how arousal can modulate response inhibition. Two competing hypotheses can be drawn from previous literature. One holds that alerting cues that elevate arousal should result in an impulsive response and therefore impair response inhibition. The other suggests that alerting enhances processing of…

Previous electromyographic studies have reported that individuals with autism spectrum disorders (ASD) exhibited atypical patterns of facial muscle activity in response to facial expression stimuli. However, whether such activity is expressed in visible facial mimicry remains unknown. To investigate this issue, we videotaped facial responses in…

Music-based technology is frequently included in early childhood classrooms as an attempt to incorporate music education in the curriculum. However, there is a lack of research that addresses the educational benefits of music-based tablet applications (apps) for young children. Researchers in this study explored the preferences of 4-year-old…

In task switching, a common result supporting the notion of inhibitory processes as a determinant of switch costs is the occurrence of "n"-2 repetition costs. Evidence suggests that this effect is not affected by preparation. However, the role of preparation on preceding trials has been neglected so far. In this study, evidence for an…

Task-cuing experiments are usually intended to explore control of task set. But when small stimulus sets are used, they plausibly afford learning of the response associated with a combination of cue and stimulus, without reference to tasks. In 3 experiments we presented the typical trials of a task-cuing experiment: a cue (colored shape) followed,…

Infants enter the world prepared to learn about their environments and to become effective social partners, while most parents are equally prepared to support these early emergent skills. Through subtle, non-conscious behaviors, parents guide their infants in the regulation of emotions, language acquisition, and participation in social exchanges.…

Hemisphere-specific processing of laterally presented global and local stimulus levels was investigated by (a) examining interactions between the visual field of stimulus presentation and the response hand and (b) comparing intra- with inter-hemispheric effects of level priming (i.e. faster and more accurate performance when the target level…

The separate effects of stimulus and response relative frequency were studied in two choice reaction time tasks containing many: 1 stimulus-response (S-R) mappings and 2 levels of S-R compatability. (Editor)

Observation of eight-month-olds (N=7) during isolated free play session with three toys revealed that significantly more vocalizations were present during transition periods where changes from locus of attention and changes in facial expression occurred. (Author/CB)
