Habituation of subjective anxiety during flooding in imagery

Patterns of habituation of subjective anxiety during flooding in fantasy are delineated for eleven obsessive-compulsive and six agoraphobic patients. The majority showed a curvilinear pattern of subjective anxiety response, while three patients showed a linear decelerating pattern. Habituation was found both within and across sessions. The results are compared with habituation patterns in physiological responses during flooding in fantasy and in vivo.     

Interactive processes in sentence comprehension and recognition

Two experiments examined the roles played by semantic and surface information in reading and recognizing sentences. Subjects read sentences in normal and inverted typography. Their recognition of meaning and other sentence features was tested using sentences whose typography, wording, and/or meaning were either the same as or different from that in the first set of sentences. In Experiment 1, subjects either read aloud or performed a sentence continuation task. For originally inverted sentences, recognition of meaning was high, irrespective of task demands. For originally normal sentences, recognition was low for Read Aloud subjects and high for Sentence Continuation subjects. Sentence recognition was affected by repetition of wording and typography. Experiment 2 replicated the results with the read aloud task and showed the second reading of originally inverted sentences to be equally swift for paraphrase and verbatim test forms. It was concluded that reading and recognition are interactive processes, involving conceptually driven and data driven operations. The interaction of operations may be either automatic or controlled. While processing of normal typography is automatic, inverted typography induces controlled processing, resulting in better retention. Furthermore, semantic and surface information are conceptualized as interacting components of comprehension and memory processes.     

Priming effects with food and water reinforcers in hamsters

Hamsters were tested in a square maze with either food or water in each corner compartment. A substantial priming effect (runway times increase as intertrial interval increases) was demonstrated using both food and water reinforcers. A lengthy period of free access to food and water (satiation) immediately abolished the priming effect, although runway times in general remained relatively rapid for some time. Extinction of rapid runway times proceeded more slowly under food than under water deprivation. It is concluded that priming is a widespread phenomenon associated with the presentation of a reinforcing stimulus to an appropriately deprived animal.     

Response conflict theory,error rates and hybrid processing: A reply to McLeod

McLeod (1977) has proposed a parallel processing model of the psychological refractory period quite similar to an earlier model most recently adumbrated by Kantowitz (1974a). This article corrects some erroneous statements made by McLeod about the testability of the response conflict model and emphasizes the importance of error data in distinguishing among conceptually similar models of the PRP effect.     

Attribution and aggression: The misattribution of anger

An experiment was designed to test the effect of misattribution of anger on subsequent aggression. Subjects were induced to take a placebo with half of the subjects led to expect arousal symptoms and the other half led to expect relaxation. Crosscutting the pill manipulation, half of the subjects were provoked by a confederate and half were not. All subjects were then given an opportunity to aggress against the confederate. As predicted, relaxation pill-provoked subjects were significantly more aggressive than subjects in the other conditions (p < .025), with arousal pill-provoked subjects no more aggressive than no provocation controls.     

The infant's acquisition of knowledge of bimodally specified events

Four-month-old infants viewed, for a duration of several minutes, two objects that bounced in synchrony with two percussion sounds. This synchrony was the only information tying each sound to its respective object. During the viewing the infants learned about the relationships between sound and object. Learning was revealed in two ways. In a search test, infants looked for an object when its sound was played. In a transfer test, infants' declining interest in a sound presented alone generalized to the visible object that the sound specified. Studies that reversed the spatial locations of the objects revealed that sound-object learning, rather than place or response learning, guided infants' perceptual exploration.     

Effect of mutual acquaintance on the construction of conversation

In a previous investigation, we demonstrated the role of questions as an instructional resource in the social construction of conversation by depriving conversationalists of their use. The resulting conversational structure, measured in terms of the ability of third parties to reconstruct the dialogues after they had been randomized, was impaired. The importance of culturally shared knowledge for the reconstruction (and by implication the construction) task was apparent in the superiority of British over Canadian subjects in reconstructing unconstrained British dialogues. The present study was concerned with the effects of privately shared knowledge on the construction of conversation. Conversational structure and the frequency of questions were greater in strangers' than in mutual acquaintances' unconstrained dialogues. Strangers' dialogues, but not those of mutual acquaintances, were disrupted under a ban on questions. The results were taken to indicate that strangers need to provide one another with continual instruction in how to proceed, whereas mutual acquaintances, in virtue of their privately shared social knowledge, can construct orderly dialogue with less moment-to-moment guidance.
