Unconscious sensations

D. M. Armstrong proposes to explain the possibility of unconscious sensations by means of a distinction between the perceptual consciousness, which is essentially involved in sensations, and our introspective consciousness of sensations. He holds that unconscious sensations are instances of perceptual consciousness of which we are not introspectively conscious. I contend that, although Armstrong's distinction is plausible and significant, it fails to explain his own examples of unconscious sensation. I argue that the puzzle of how unconscious sensations are possible arises at the level of perceptual consciousness and does not concern our introspective awareness of mental states.This paper grew out of research supported by the National Endowment for the Humanities at Cornell University in 1985. I would like to express my gratitude to the National Endowment, to Cornell, and to Sydney Shoemaker.     

Memories of statements spoken in everyday contexts

This study examined personal memories of statements spoken in everyday contexts. Eighty college students completed a questionnaire in which they recounted the first spoken statement to come to mind, and statements made by a parent, teacher, sibling and friend. Respondents also provided information about the speakers and the circumstances of transmission. Content analyses identified six primary statement types: rules, evaluations, speaker information, pronouncements, unusual phrases and everyday speech. The incidence of different statement types varied across speakers. Memorability of a specific verbalization appears to be related to the statement's communicative function, the listener's reactions to the utterance, the speaker's gender, and the relationship between the speaker and the listener.     

Paired associate learning in reading-disabled children: evidence for a rule-learning deficiency

Two experiments examined whether normal and disabled readers differed in the utilization of rules in a paired associate learning task. Experiment 1 required children to learn symbol-word associates. Children were assigned to one of three conditions: nonrule, consistent rule, or inconsistent rule. When present, the rule was based on semantic opposites. Subjects benefited from having the rule, but disabled readers showed less improvement across four test blocks than both chronological age (CA) controls and reading age (RA) controls, particularly in the inconsistent condition. Experiment 2 required subjects to learn symbol-symbol associations in one of three conditions: nonrule, consistent rule, or inconsistent rule. When present, the rule specified the locations of a subsidiary figure in each symbol according to the pattern top-right, bottom-left. Disabled and normal readers did not differ in the nonrule condition where reliance on visual memory would be an effective strategy. Normal readers were superior to disabled readers in both rule conditions. In addition, disabled readers in the inconsistent rule condition were less able than normal readers to apply the rule in a generalization task where memory demands were reduced. Results supported the hypothesis that disabled readers have greater difficulty than normal readers inducing and/or using rules, particularly when they are inconsistent. It is suggested that difficulties in acquiring or using complex and inconsistent rules may be one important source of problems learning spelling-sound correspondence rules, which in English are complex and inconsistent.     

The Interaction of Psychosocial and Biological Determinants of Tobacco Use: More on the Boundary Model1

We refine our Boundary Model of the regulation of drug intake and apply it to several examples from cigarette smoking. Our model demands the simultaneous consideration of biological and psychosocial controls. The biological factors include the physiological demand to maintain minimum levels of nicotine, direct rewarding effects of tobacco, and toxic effects of excessive smoking. The psychosocial factors include “voluntary”, self-initiated controls as well as situational influences. In light of the model, we review and consider the problems with techniques commonly used to control smoking, and we discuss the inferential confusions faced by smokers and researchers.     

The Psychology of Restaurant Tipping1

Since its origins in 18th-century English pubs, tipping has become a custom involving numerous professions and billions of dollars. Knowledge of the psychological factors underlying tipping would benefit service workers, service managers, and customers alike. Two studies were conducted to provide such knowledge about restaurant tipping. The percent tipped in these studies was related to group size, the customer's gender, the method of payment (cash or credit), and in some cases, the size of the bill. Tipping was not related to service quality, waitperson's efforts, waitperson's gender, restaurant's atmosphere, or restaurant's food.     

An Adlerian understanding of Hillel's maxim

Hillel, one of Judaism's great scholars and sages, has amongst his many statements, one which is most well known and has withstood the test of time. With this statement, he has shown an insight into human psychology that anticipated today's modern approach toward understanding behavior, particularly when using an Adlerian interpretation of his maxim.Rabbi Steven J. Kaplan, Ph.D. is Hillel Director, University of Southern Florida-University of Tampa. He may be addressed at the University of Southern Florida, CTR 2382, Tampa, Florida 33620.     

Home background,intelligence, personality and education as predictors of unemployment in young people

This study is concerned with the degree to which youth unemployment in N. Ireland can be predicted from a number of antecedent variables. It was found that home background, IQ, personality, school type and educational attainments all had significant effects on unemployment. The magnitude of the effects and the causal mechanisms through which they operate were analysed by path analysis in terms of the Duncan-Jencks path-analysis model. The results show that the model holds well for N. Ireland; the major difference is that school type (grammar vs secondary modern) plays a greater role in N. Ireland than school differences in the U.S.A. The data are considered from the point of view of the intergenerational cycle of deprivation hypothesis. It was found that using the criteria of father-son and father-daughter correlation for unemployment, the cycle is quite weak in N. Ireland.     

Does imagery contribute to metaphoric quality?

With metaphoric quality divided into an appropriateness and novelty component, college-student subjects rated 75 metaphoric sentences on those components and on imageability. Different subjects were assigned to each of the three rating conditions (n=45 in each). Correlations based on mean ratings of the metaphors indicated that imageability was negatively related to novelty and positively related to appropriateness. A composite of the novelty and appropriateness ratings (deemed to reflect metaphoric quality) proved to be independent of imageability. Examination of metaphors with the highest and lowest imagery ratings suggested that imagery was facilitated by perceptual-configural linkages and inhibited by remote conceptual linkages between topic and vehicle. This configural-conceptual distinction appears to be of greater importance than quality in influencing the extent to which a metaphor is imaged.An earlier version of this paper was presented by the first author at the Annual Meeting of the Eastern Psychological Association, New York City, April 1981. This research was funded in part by a doctoral fellowship from the Social Sciences and Humanities Research Council of Canada to the first author, who is now affiliated with the University of Illinois.     

Function of intertrial interval in matching-to-sample

Twelve pigeons were trained on matching-to-sample using either a 0-, 5-, 15-, 25-, or 60-sec intertrial interval. Eight of these 12 pigeons were given one of the following intertrial interval changes: 0 to 60, 0 to 5, 5 to 0, 60 to 0, 15 to 25, 5 to 15, 60 to 5, 5 to 1, 1 to 5, 1 to 25, and 25 to 1 sec. Most intertrial interval changes were repeated at least once. The 0-sec intertrial interval subjects failed to match beyond chance levels, while other intertrial interval values resulted in matching acquisition. Changes from 0 sec to other intertrial interval values increased and changes to 0 sec decreased matching performance. Changes to intertrial interval values other than 0 sec resulted in little change in matching accuracy once stable performance had been attained.     

PROGRAM EVALUATION RESEARCH: AN EXPERIMENTAL COST-EFFECTIVENESS ANALYSIS OF AN ARMED ROBBERY INTERVENTION PROGRAM

An armed robbery alarm system was implemented in 48 different stores in two separate geographical areas for 6 months and 12 months, respectively. The alarms were placed in the two separate areas at different times and all alarms were eventually removed. Thus, multiple baseline and reversal strategies were used to evaluate program impact. A device planted in a cash drawer was triggered whenever “bait” money was removed from the drawer sending an alarm signal directly to police cars and headquarters. Onscene apprehensions of armed robbers within target stores were greatly increased even though the armed robbery systems did not deter robbery incidents nor influence the court disposition of the cases. There was also no crime deterrence, crime displacement, or increased apprehensions in either the immediate neighborhoods of target stores or on a city-wide basis. The cost effectiveness of the program was calculated to be poor even though the program is being maintained because of the absence of an alternative robbery apprehension technology.
