Visual imagery: A case study

This paper describes the performance of a subject who, when presented with a word or a sentence, is abnormally proficient at spelling this material in reverse order. She reports that she does this by visualizing this material and reading off from this visual image. Her tachistoscopic performance is also abnormally good. It is suggested that her superiority in these two tasks is achieved principally because her internal visual representations are extremely resistant to disruption by other mental activities.     

John McDowell on Experience: Open to the Sceptic?

The aim of this paper is to show that John McDowell's approach to perception in terms of "openness"remains problematically vulnerable to the threat of scepticism. The leading thought of the openness view is that objects, events and others in the world, and no substitute, just are what is disclosed in perceptual experience. An account which aims to defend this thought must show, therefore, that the content of perceptual experience does not "all short" of its objects. We shall describe how McDowell defends the openness view with reference to the disjunctive analysis of appearances (sections II and III); argue that his defence includes features which are both inconsistent with and unnecessary for the openness view (section IV); and show how those features call into question the success of McDowell's route of response to sceptical arguments (section V). Finally, we sketch an alternative approach to openness and conclude that the explosive effect of letting loose the conception of experience advanced by the openness view has yet to be felt in the English-speaking world (section VI).     

Verification of Statements about Story Worlds That Deviate from Normal Conceptions of Time: What Is True aboutEinstein''s Dreams?

College students read chapters from a novel written by Alan Lightman (Einstein's Dreams) and later provided verification judgments on the truth/falsity of test statements. Each chapter described a different fictional village that incorporated assumptions about time that deviate from our normal TIME schema, e.g., citizens knowing exactly when the world will end, time flowing backward instead of forward. These novel assumptions about time provided interesting insights about life and reality. In two experiments, we examined whether readers could accurately incorporate these novel assumptions about time in the fictional story worlds, as manifested in the verification judgments for statements after story comprehension. The test statements included verbatim typical, verbatim atypical, inference typical, and inference atypical information from the perspective of mundane reality that meshes with a normal TIME schema. Verification ratings were collected on a 6-point scale in Experiment 1, whereas Experiment 2 used a signal–response technique in which binary true/false decisions were extracted at −.5, 1.5, 3.5, 5.5, and 10.0 s. The college students were measured on literary expertise, reading skill, working memory span, and reading time. Readers with comparatively high literary expertise showed truth discrimination scores that were compatible with aschema copy plus tagmodel, which assumes that readers are good at detecting and remembering atypical verbatim information; this model predicts better (and faster) truth discrimination for verbatim atypical statements than for verbatim typical statements. In contrast, fast readers with comparatively low literary expertise were compatible with afilteringmodel; this model predicts that readers gloss over (or suppress) atypical verbatim information and show advantages for verbatim typical information. All groups of readers had trouble inferentially propagating the novel assumptions about time in a fictional story world, but the slower readers were more accurate in their verification of the atypical inferences. Aconstruction–integrationmodel could explain the interactions among literary expertise, reading time, and the typicality of test statements.     

Criteria used in the selection of students for school psychologist training programs

A questionnaire regarding criteria used in the selection of students for school psychologist There were 63 responses. Undergraduate scholastic index was the most frequently used criterion, followed by undergraduate psychology index, letters of recommendation, and GRE scores. The interview, used by half of those reporting, was not employed consistently. The MAT was used by less than half of the respondents, and ranked lower in importance. Most universities used four or five criteria for admission. No respondents required teaching experience.     

Sex of leader and subordinate role stress: A field study

This research examines the relationship between sex of leader and subordinate perceptions of two dimensions of role stress — role conflict and role ambiguity — as moderated by subordinate job level, age, and sex. Interaction effects for sex of leader also are investigated. Subjects are 184 supervisory and nonsupervisory employees of a psychiatric hospital. Results suggest that sex of leader does not significantly affect subordinate role conflict and role ambiguity. Most interactions were nonsignificant.     

Phonological recoding and lexical access

Four experiments are reported that examine the effects of homophony (e.g., SAIL/SALE) on response latency in a lexical decision task. The results indicated that an effect of homophony was evident only if the nonword distractors consisted of legal, pronounceable strings (e.g., SLINT), but that this effect disappeared if the nonwords sounded like English words (e.g., BRANE). An optional encoding strategy is proposed to account for this differential effect. It is suggested that while both graphemic and phonemic encoding occurred simultaneously, naive subjects tended to rely on the outcome of the phonological route. However, when such reliance produced a high error rate (i.e., when the nonwords sounded like English words),. these subjects were able to abandon a phonological strategy and rely on the graphemic encoding procedure instead. Two further aspects of the results are of interest. First, the less frequent member of a homophone pair was slower when compared with a control item if the nonword distractors were of the SLINT type, but not different if they were of the BRANE type. The high-frequency members did not differ from their controls in either nonword environment. Second, in a homophone “repetition” experiment, the frequency order of presentation within pairs of homophones (i.e., the high-frequency member followed by the low-frequency member, or vice versa) had a substantial effect. A spelling recheck procedure and a response-inhibitory mechanism are postulated to incorporate these effects into a dual-encoding direct-access model of word recognition.     

A miniprocessor PDP8/e-based system for investigations of on-line language processing: Automated program for psycholinguistic experiments (APPLE)

An on-line reaction time program designed for psycholinguistics research implemented on a DEC PDP8/e minicomputer is described. Current applications include: phoneme monitor, click detection, lexical decision, and sentence verification experiments. This assembly language program (PAL8) displays alphanumeric texts on remoted oscilloscopes and records decision-dependent response times with 1-msec accuracy. The system allows for simultaneous testing of three subjects. It operates either according to internally generated timing or in synchrony with audio tape. Individuals with little or no computer background can develop and run experiments without difficulty.     

The technique of path coefficients

A derivation of equations fundamental to the technique of path coefficients is given. Suggestions are made with respect to the calculations required in the use of the technique. The relations of the technique to those of partial correlation, semi-partial correlation, part correlation, multiple correlation, and factor analysis are discussed. Some consideration is given to the merits and limitations of the technique of path coefficients.
