Mandel, Natalie R.; Cividini-Motta, Catia; Schram, Jeffrey; MacNaul, Hannah – Journal of Applied Behavior Analysis, 2022
This study examined if listener behavior and responding by exclusion would emerge after training 3 participants with autism to tact stimuli. Tacts for 2 of 3 stimuli were directly trained using discrete trial training methodology and were followed by an auditory-visual discrimination probe in which auditory-visual discrimination by naming (i.e.,…

Bourret, Jason C.; Iwata, Brian A.; Harper, Jill M.; North, Stephen T. – Journal of Applied Behavior Analysis, 2012
Five individuals with autism or other developmental disabilities participated in paired-stimulus preference assessments during repeated baseline probes. All subjects initially showed a pronounced bias by typically selecting the stimulus placed in either the left or right position. Biased responding for 3 subjects was eliminated when training…

Reed, Sarah R.; Stahmer, Aubyn C.; Suhrheinrich, Jessica; Schreibman, Laura – Grantee Submission, 2013
Stimulus overselectivity is widely accepted as a stimulus control abnormality in autism spectrum disorders and subsets of other populations. Previous research has demonstrated a link between both chronological and mental age and overselectivity in typical development. However, the age at which children are developmentally ready to respond to…

Gabay, Shai; Chica, Ana B.; Charras, Pom; Funes, Maria J.; Henik, Avishai – Journal of Experimental Psychology: Human Perception and Performance, 2012
Inhibition of return (IOR) is modulated by task set and appears later in discrimination tasks than in detection tasks. Several hypotheses have been suggested to account for this difference. We tested three of these hypotheses in two experiments by examining the influence of cue and target level of processing on the onset of IOR. In the first…

Oberfeld, Daniel; Hecht, Heiko – Journal of Experimental Psychology: Human Perception and Performance, 2008
The effects of moving task-irrelevant objects on time-to-contact (TTC) judgments were examined in 5 experiments. Observers viewed a directly approaching target in the presence of a distractor object moving in parallel with the target. In Experiments 1 to 4, observers decided whether the target would have collided with them earlier or later than a…

Tollner, Thomas; Gramann, Klaus; Muller, Hermann J.; Kiss, Monika; Eimer, Martin – Journal of Experimental Psychology: Human Perception and Performance, 2008
In cross-dimensional visual search tasks, target discrimination is faster when the previous trial contained a target defined in the same visual dimension as the current trial. The dimension-weighting account (DWA; A. Found & H. J. Muller, 1996) explains this intertrial facilitation by assuming that visual dimensions are weighted at an early…

Poplu, Gerald; Ripoll, Hubert; Mavromatis, Sebastien; Baratgin, Jean – Research Quarterly for Exercise and Sport, 2008
The aim of this study was to determine what visual information expert soccer players encode when they are asked to make a decision. We used a repetition-priming paradigm to test the hypothesis that experts encode a soccer pattern's structure independently of the players' physical characteristics (i.e., posture and morphology). The participants…

Forster, Jens – Journal of Experimental Psychology: General, 2009
Nine studies showed a bidirectional link (a) between a global processing style and generation of similarities and (b) between a local processing style and generation of dissimilarities. In Experiments 1-4, participants were primed with global versus local perception styles and then asked to work on an allegedly unrelated generation task. Across…

Chen, Zhe; Cave, Kyle R. – Journal of Experimental Psychology: Human Perception and Performance, 2006
What happens after visual attention is allocated to an object? Although many theories of attention assume that all of its features are selected and processed, there has been little direct evidence that an irrelevant feature dimension of an attended nontarget is processed. In 5 experiments presented here, the authors used a singleton paradigm to…

Brune, Camille W.; Woodward, Amanda L. – Journal of Cognition and Development, 2007
In this study, we investigated relations between infants' understanding of intentional actions and measures of social responsiveness during a transitional period, 9- to 11-months. Infants (N = 52) were tested in visual habituation paradigms tapping their understanding of the relation between a person and the object of her attention. Measures of…

This study investigated 17-week-old infants' response to discrepancy in visual patterns as a function of rate of habituation. (BRT)

Lewkowicz, David J. – Developmental Psychology, 1985
Three studies were designed to examine infants' bisensory responsiveness to temporally modulated stimulation by varying frequency while keeping intensity constant, by varying both frequency and intensity together, and by varying intensity while keeping temporal frequency constant. Findings indicate that sound influences visual preferences via…

Wolff, Peter – 1972
Several studies have indicated that children have difficulty differentiating mirror-image stimuli. In the present study adults were required to classify pairs of horseshoe stimuli as same or different. Response times were compared for stimulus pairs that varied in orientation (left-right vs up-down) and spatial plane of the pair (horizontal vs.…

Tiger, Jeffrey H.; Hanley, Gregory P.; Hernandez, Emma – Journal of Applied Behavior Analysis, 2006
The current study examined the reinforcing effects of choosing among alternatives in a four-part evaluation. In the first study, initial-link responses in a concurrent-chains arrangement resulted in access to terminal links in which the completion of an academic task resulted in (a) the choice of a reinforcer (choice), (b) the delivery of an…
