In a number of psychological studies, answers to reasoning vignettes have been shown to result from both intuitive and deliberate response processes. This paper utilizes a psychometric model to separate these two response tendencies. An experimental application shows that the proposed model facilitates the analysis of dual-process item responses…

Attempts to determine how far orthodox concept attainment tasks are representative of corresponding real-world activity. (Author/RK)

Investigates the differences between rehearsal span and memory span and evaluates the research of Dalrymple-Alford (1967) on the part of rehearsal on reinforcing memory traces. (Author/RK)

This study is the first demonstration of sequential contrast effects with human subjects during the acquisition of a discrimination without errors. Results are discussed in terms of Terrace's theory of errorless learning. (Editor/RK)

Describes a series of experiments showing that in normal subjects (a) iconic storage occurs primarily in the retina in the photoreceptors and (b) under conditions of dark pre- and postexposure fields, the icon is mainly a rod phenomenon. Draws conclusions based on these experiments, discusses previous work done by others, and attempts to reconcile…

Studies of the psychology of hindsight have shown that reporting the outcome of a historical event increases the perceived likelihood of that outcome. Three experiments show that similar hindsight effects occur when people evaluate the predictability of scientific results. Implications for the evaluation of scientific research by lay observers are…

Attempts to determine whether a sufficiently demanding and difficult interpolated task (shadowing, i.e., repeating aloud) would decrease recall for earlier-presented items as well as for more recent items. Listening to music was included as a second interpolated task. Results support views that serial position effects reflect a single process.…

Superordinate cues (e.g., "animal" for "dog") and coordinate cues (e.g., "cat" for "dog") were compared in two experiments. Associability and not the superordinate or coordinate relationship seems to be important in determining the effectiveness of cues. (Editor)

The existence of verification processes in recognition memory was confirmed in the context of Adams' (Adams & Bray, 1970) closed-loop theory. Subjects' recognition was tested following a learning session. The expectation was that data would reveal consistent internal relationships supporting the position that natural language mediation plays…

Presents evidence which, on one hand, disconfirms storage interpretations of the constituent boundary effect and, on the other hand, supports a specific retrieval interpretation. (Author)

Presents a more precise analysis of the way in which semantic constraints affect the perception of reversible sentences. (Author/RK)

Reports a series of experiments that give evidence for retention of information about color in very short-term visual memory, commonly termed "iconic memory". (Author)

Investigates the effect of specificity on retention following nonsemantic processing. Five experiments are reported in which structural specificity was manipulated along with either phonemic or orthographic dimensions, and process specificity was manipulated by variations in the nonsemantic orienting tasks. Data are interpreted in terms of a…

Examines the effects of consensus information on the prediction of behavior as a function of social desirability of consensus information and the presence or absence of vignette information about target persons. Discusses the different manners in which consensus information can be used. (Author/RK)

While there has been considerable success in isolating the dimensions of acoustic information that are important in perceiving and identifying speech sounds, very little is known about how the information from the various acoustic dimensions is put together in order to actually accomplish identification. Proposes and tests a model of these…
