Twenty 7-10 year old children with spina bifida cystica and hydrocephalus and 20 normals matched for age, sex and IQ were compared on a 12-trial target task, first used by Connolly, Brown & Bassett (1968). Findings are discussed in relation to neurological abnormalities in the spina bifida group. (Editor/RK)

Paranoid and nonparanoid schizophrenics were compared to normals in their performance on a sentence verification task. Results were related to past evidence and hypotheses about central processing performance among schizophrenics. (Editor/RK)

Biofeedback was contrasted with a false-feedback condition to examine the pure effect of the former on tension headache. (Author/RK)

Compares the effects of the "relative novelty" (Berlyne, 1960) of stimuli on the level of attention and rate of habituation in antisocial and neurotic children. (Author/RK)

Data replicate and extend research on differences in physiological patterning between psychopaths and control subjects and provide new information on patterning with instructions and learned specificity with biofeedback. (Author/RK)

If animals receive inescapable electric shocks, their subsequent avoidance-escape learning is poor. This phenomenon, which can be called "the interference effect", was studied in four experiments. (Editor)

Investigates how the inhibition and latency-reduction effects interact with each other and how they change with changes in the intensity of the startle-eliciting stimulus. (Author/RK)

If half of the items in a list are repeated over a series of trials while the remainder of the items are new on each trial, recall of the repeated items is impaired. Two experiments examined the list context effect and a list differentiation interpretation was supported. (Editor/RK)

Attempts to develop a method for investigating the process of phonemic encoding and explores the structural and linguistic variables that influence the length of time required for phonemic translation of sequences of graphemes. (Author/RK)

Although a feature detection theory of pattern recognition is consistent with many recent physiological findings, the specific rules governing the perception of the distinctive features of letters have not yet been determined. This article presents two new experimental procedures for determining these rules. (Editor)

Three converging procedures were used to determine whether pictures presented in a rapid sequence at rates comparable to eye fixations are understood and then quickly forgotten. (Editor)

Tulving and Thomson's encoding specificity effect was examined as a function of grammatical class and concreteness of the cues. (Editor)

Describes the idea of behavioral objectives and their positive uses in the classroom. (Author/RK)

The present research represents an initial attempt to compare the results obtained using artificial information with results obtained in a typical semantic memory experiment. (Editor)

Subjects were required to discriminate previously learned "standard" versions of angular shapes from randomly perturbed "distrator" versions that varied in similarity to the standard. (Editor)
