Play and cognition: Studies of pretence play and conservation of quantity

Study 1 examined the relative effectiveness of four different training conditions on the attainment of conversation of quantity. Subjects were 75 nonconserving preschoolers, ranging in age from 3.10 to 5.0 years. Treatment consisted of pretense play training, direct conservation training, a combination of pretense play and conservation training, mere exposure to the conservation tasks without the benefits of instruction, and a control condition which provided only conservation pre- and post-tests. The results of the two conservation post-tests indicated that a combination of pretense play and conservation training was the most effective condition, followed by the conservation training and then by the pretense play training. The data also suggested that the effects of the conservation-only training condition might be less stable than those attained with pretense play training. Study 2 compared the effectiveness of child initiated pretense play training with adult initiated play. Subjects were 47 nonconserving children ranging in age from 4.0 to 5.8. Treatment consisted of child initiated pretense play, adult initiated play, a condition which combined both treatments, and a control group. The results of the two conservation post-tests indicated that the child initiated pretense play training was most effective, followed by the combined condition and by the adult initiated training. The three pretense play training conditions induced significantly more conserving responses in previously nonconserving children than the control group.     

Dissociations in aphasia: A case report

This paper is a case study of an aphasic patient who displays two interesting characteristics, namely, (1) a dissociation between his oral and written disorders (i.e., oral Wernicke vs. written Broca); (2) an agraphia-alexia syndrome in which the picturability of the entities referred to by words plays an important role. Some of the characteristics shown by this patient have been well described concerning reading but never concerning writing. This second aspect is particularly emphasized.     

Antecedents to Fechner's law: the astronomers J. Herschel, W. R. Dawes, and N. R. Pogson

The history of the stellar magnitude scale is briefly traced from the second century b.c. until the middle of the nineteenth century. It becomes clear that astronomers formulated "Fechner's Law" by about 1850. While Fechner is credited with the grander view of things, the contention is made that the astronomers John Herschel, W. R. Dawes, and N. R. Pogson have not been given their due by historians of psychology.     

Operant theory and methodology in infant vocal conditioning

The numerous mechanisms of behavior change in infant development are sometimes difficult to distinguish. Although it is agreed that elicitation and reinforcement both influence infant learning, the distinction between these two learning mechanisms was clarified in response to K. Bloom's (1984, Journal of Experimental Child Psychology, 38, 93-102) commentary. The theoretical and methodological assumptions of an functional analysis of infant behavior were made explicit in the context of the C. L. Poulson study (1983, Journal of Experimental Child Psychology, 36, 471-489). The rationale for the use of DRO schedules to control for elicitation effects of continuous reinforcement and the inadequacy of noncontingent schedules for this purpose were also discussed.     

Cardiac deceleration in newborns: habituation, dishabituation, and offset responses.

Twenty healthy, 1–4 day-old infants were selected from a sample of 135 neonates on the basis of alertness during testing. The infants were presented mild intensity colored light with gradual onset and offset while heart rate was monitored. Half the infants received six exposures to blue light followed by two exposures to blue-green light, whereas remaining subjects received colors in reverse order. Stimulus duration was 20 sec and variable periods between stimuli averaged 30 sec. Results of trend analysis of variance of the second-by-second cardiac data indicated that for infants older than the median age, the decelerative responses to both stimulus onset and offset were significant. Further, these subjects' onset decelerations significantly habituated within the six stimulus repetitions and significantly dishabituated with change in the stimulus color. Offset decelerations incremented over habituation trials and decremented with change in stimulus color. Responses of younger subjects were more variable which probably reflects their less complete recovery from the effects of maternal medication and the birth process.     

Controllability and human stress: method, evidence and theory.

Concepts are defined and evidence reviewed on whether control reduces stress in man. Individuals seem to prefer instrumental control over an aversive event, seem to prefer to administer it to themselves, and are less aroused when waiting for a controllable event. When groups without control have equal predictability, having control is still less arousing; as potential (but unexercised) control seems to be. The evidence also suggests that controllable events may hurt less. Methodological weaknesses and empirical gaps in these data are pointed out. These data are grossly inconsistent with Relevant Feedback theory and rather inconsistent with Information-seeking theory and Safety Signal theory. A Minimax hypothesis is proposed: When individuals control aversive events, they believe relief to be caused by a stable source—their own response. This belief entails that maximum future danger will be minimized. When they have no control, they believe relief to be less stable, which entails no guarantee that maximum future danger will be minimized. The data are largely consistent with the Minimax hypothesis and wholly consistent when Minimax is supplemented by the premise that aversive events hurt less when encountered against a background of relaxation.     

Bilateral tachistoscopic perception,handedness, and laterality: II. Nonverbal stimuli

Thirty-two Subjects were assigned to four groups on the basis of handedness (left or right) and familial sinistrality (absent or present). Their laterality patterns were investigated with a cued order-of-report paradigm. On each trial, Subjects saw a tachistoscopic presentation of two outline drawings of common objects, one drawing on the left of a central fixation point, one on the right. A centered arrowhead appeared with the pictures; the arrowhead pointed either left or right, and its direction indicated the order of report. The results for each group were discussed in terms of asymmetry for rate of processing and rate of decay, and in comparison with our earlier study of word recognition.     

Differential reinforcement of other-than-vocalization as a control procedure in the conditioning of infant vocalization rate

The purpose of the present study is to demonstrate reinforcement control over infant vocalization rates using a DRO schedule to control for elicitation of social stimulation. Mothers of four 2 1/2- to 3-month-old infants provided social reinforcement for their infants' vocalization under two schedules: continuous reinforcement (CRF) and differential reinforcement of other-than-vocalization (DRO). In a repeated-reversal single-subject experimental design, all four infants produced systematically higher vocalization rates during CRF, even though densities of social stimulation during DRO were equal to or greater than densities provided during CRF. Thus, whatever its elicitation value, social stimulation may reinforce infant vocalization rates.

The results of the study are commented upon, and implications for the continuing controversy about the effects of early childhood intervention are suggested.     

Language,Behaviour, and Empathy. G.H. Mead’s and W.V.O. Quine’s Naturalized Theories of Meaning

ABSTRACT

The paper compares Mead’s and Quine’s behaviouristic theories of meaning and language, focusing in particular on Mead’s notion of sympathy and Quine’s notion of empathy. On the one hand, Quine seems to resort to an explanation similar to Mead’s notion of sympathy, referring to ‘empathy’ in order to justify the human ability to project ourselves into the witness’s position; on the other hand, Quine’s reference to the notion of empathy paves the way to a more insightful comparison between Mead’s behaviourism and an explanation of the emergence of the linguistic from pre-linguistic communication based on empathic identification processes. However, Mead is less ambiguous than Quine in his use of the notion of sympathy finds a fecund parallel in the current neuroscientific and neuro-phenomenological hypothesis on ‘empathy’. The article contends that the ambiguity in Quine’s account of empathy is due to the exigency of trying to elucidate the link between the rules of language in a cultural context and the natural, that is ‘instinctive’, basis of the process of learning a language. This is the reason why his epistemological behaviourism is particularly close to the non-reductionist naturalism of Mead. The working hypothesis proposed in the conclusion deals with the core notions of ‘gesture’ and ‘behaviour’.     

Sidney w. Bijou: the illinois years, 1965-1975

Sidney W. Bijou is among the founders of behavior analysis, but the record of his contributions is incomplete. It has not systematically described his contributions beyond his tenure at the University of Washington (1948-1965). The purpose of this paper is to describe his contributions over the course of the next decade-his years at the University of Illinois (1965-1975). I begin by reviewing his education and training, contributions at Washington, and why he left and moved to Illinois. Then, I describe his Illinois years: his appointments, colleagues, and service; the Child Behavior Laboratory; grant funding and publications; further service, awards, and recognition; and influence on his colleagues, students, classroom teachers and research supervisors, and visiting scholars. Bijou is modest about his contributions at Illinois, but he advanced the field in many ways over the course of the decade, especially the careers of his colleagues and students.     

Individual differences in speed of phonemic analysis, visual analysis, and reading.

College student subjects (Ss) classified phrases as making sense or not according to sound in one condition, according to visual appearance in another, and in abasic task in which either strategy would yield right answers. Ss who were relatively fast in the visual condition were faster at the basic task than Ss who were relatively fast in the sound condition. Other results suggested that the former Ss used a visual strategy in the basic task while the latter used a phonemic strategy.
