“Consistency” and “contradiction” in the development of gender role characteristics

There is currently an increasing amount of theoretical and empirical work arguing that stereotyped sex role behavior is maladaptive in our culture and that “androgyny” or “sex role transcendence” is a preferred mode of being. The latter, however, seems to require individual inconsistency and self-contradiction in behaviors and attitudes (since the individual is both active and passive, both independent and dependent, etc.). Theories of cognitive consistency maintain that individuals avoid self-contradiction and inconsistency, and therefore that androgyny runs counter to important motivational principles. This article examines this issue in some detail, and concludes that theories of cognitive dissonance and consistency reflect particular socio-cultural conditions rather than universal motivation principles. There is nothing inherently uncomfortable or “inconsistent” about androgyny and sex role transcendence.     

Effects of visual familiarity on “same” and “different” decision processes

An experiment was conducted in which subjects matched upper and lower case versions of well-known abbreviations, such as BBC and etc, and meaningless controls. “Same” RT showed a familiarity effect for upper case versions of abbreviations such as BBC and GPO, but not for the lower case versions bbc and gpo. The converse did not occur for abbreviations such as etc, which were thought to occur most frequently in lower case. The “different” RT was inhibited by familiarity, with pairs such as IBM GPO being classified less rapidly than their lower case versions or controls. These effects occurred for subjects instructed to report “No” for “same” displays and “Yes” for “different” displays as well as for subjects given a conventional decision-report assignment. Some implications of these results for an account of the manner in which familiarity affects graphemic comparison processes are considered.     

A study of position habits induced by reward and “frustration”

Predictions from Maier's theory of “frustration”-instigated behaviour have been tested in an experimental situation differing significantly from that in which the theory was propounded yet containing the central element of “frustration”—the insoluble problem.

A water discrimination unit was employed in which the performance of rats would be observed during attacks on insoluble problems, position problems or symbol problems.

Two groups, each containing ten Wistar albino rats, served as subjects. The research design consisted of the following phases: preliminary training, development of position responses, exposure to a symbol-reward problem with 50 per cent, punishment and exposure to a symbol-reward problem with 100 per cent, punishment. The design differed for the two groups only at the phase in which the position responses were established. During this phase one group was exposed to a position-reward problem and the other to an insoluble problem.

Position responses were established as frequently under position-“frustration” (position stereotypes) as under position-reward (position habits) conditions. Position stereotypes were more rigid—more resistant to extinction—than position habits under conditions of 50 per cent, punishment. Position stereotypes were as readily extinguished under 100 per cent, punishment as were position habits under 30 per cent, punishment.

The first two observations conform to predictions made from Maier's theory. The third does not. That is to say, not all situations containing the basic elements of “frustration” give rise to stereotyped behaviour patterns which are as rigid or “fixated” as Maier's theory would predict. It is a reasonable hypothesis that the characteristics of stereotyped responses established in certain “frustration” situations may be described adequately in terms of conventional learning principles without the necessity of resorting to a distinction between “goal-motivated” and “frustration-instigated” behaviour.     

An assessment of the potential utility of “scientific jury selection”: A “thought experiment” approach

The efficacy of “scientific jury selection” (the use of social science methodology to aid the jury selection process) has been a subject of considerable contention. Unfortunately, such issues are difficult to address empirically, especially at the level of jury rather than juror decisions. One means of addressing some of these questions is through the use of “thought experiments” or computer simulations that are based not on intuition or conventional wisdom alone but guided by relevant empirical data. This paper reports the outcomes of simulations that explore jury verdict consequences from the use of scientific jury selection to (a) obtain changes in venue, (b) select jurors, and (c) accomplish both of the preceding. The results indicated that the potential effects of scientific jury selection are strongest when the techniques are successful in bringing about changes of venue or more representative jury panels. Somewhat weaker, albeit still consequential, effects were observed in those instances where scientific jury selection techniques are used to select particular jurors. The psychological and legal implications of these results, and the thought experiment approach in general, are discussed.     

The contribution of “cool” and “hot” components of decision-making in adolescence: Implications for developmental psychopathology

Impairments in either “cool” or “hot” processes may represent two pathways to deficient decision-making. Whereas cool processes are associated with cognitive and rational decisions, hot processes are associated with emotional, affective, and visceral processes. In this study, 168 boys were administered a card-playing task at ages 13 and 14 years to assess response perseveration. This task was designed to initially reward playing and gradually associate playing with punishment. Measures of subjective ordering (cool processes) and neuroticism (hot processes) at age 13 years were used to examine how these individual characteristics relate to perseveration over time. A decrease in perseveration from age 13 to 14 was associated with cool processes whereas hot processes were associated with response perseveration only over time. A complementary but simultaneous assessment of cool and hot processes, such as neuropsychological and personality tests, could facilitate treatment planning of children with behavioral problems.     

Context, categorization, and recall: The “change-of-standard” effect

A psycholinguistically based conception of the relation among context, categorization, and memory is tested by examining what happens to people's memory of an object when the object is initially categorized in terms of the context in which it appears, but, when the object is later recalled, this context is no longer salient. Subjects read about the sentencing decisions of a target trial judge in the context of other trial judges who consistently gave either higher sentences or lower sentences than the target judge. As predicted, subjects tended to categorize the target judge as “lenient” in the former, harsh context condition, and as “harsh” in the latter, lenient context condition. A week later, subjects read about the sentencing decisions of some additional judges, and then recalled the sentencing decisions of the target judge they had read about the week before. Across the two sessions, either a harsh, moderate, or lenient category norm for judges' sentencing decisions was established by having subjects read about decisions that involved either high, medium, or low sentences, respectively. The results indicated that subjects recalled the target judge's decisions by interpreting their prior categorization of his behavior in terms of the category norm established across the two sessions rather than the original context. Thus, subjects who were exposed to the same target in the same circumstances, and initially categorized the target in the same way, nevertheless remembered his behavior differently if their category norm was different at the moment of recall. Other types of “change of standard” and their implications for human judgment and memory are discussed.     

Heart rate variability and respiratory concomitants of visual and nonvisual “imagery” and cognitive style

Attention to visual and nonvisual imagery, elicited by an imagery questionnaire, was studied using both within and between subjects analyses of cardiac and respiratory parameters. Visual imagery was accompanied by more regular interbeat heart rate (HR) and shorter, more stable respiratory cycles than nonvisual imagery. “Visually-oriented” thinkers (visualizers), identified by a word association test, manifested less overall variability in HR than “verbally-oriented” thinkers (verbalizers), as well as less variable HR and respiratory period during visual imagery. Visual and nonvisual imagery differed in HR variability for verbalizers and in respiration period for visualizers. The results are discussed in terms of the concepts of attention deployment, “mental load”, cerebral asymmetry, and stylistic personality differences in cognitive functioning.     

Motivation and learning: Neurophysiological mechanisms in a “model” system

The neurophysiological mechanisms underlying behavioral motivation and associative learning are described in an invertebrate “model” system, the carnivorous marine mollusc Pleurobranchaea. Feeding motivation can be controlled via nutritional history and is represented centrally in the feeding motor network as a change in the balance of synaptic excitation and inhibition at the level of interneurons that initiate feeding behavior, i.e., feeding “command” interneurons. Associative learning, induced by avoidance conditioning of feeding behavior, manifests identically at the level of the command interneurons, but is distinguished from non-associative motivational changes by processes that occur in identified neurons and pathways presynaptic to the command interneurons. Motivation and learning are therefore linked mechanistically by convergent neurophysiological mechanisms at the level of central neurons that initiate behavior.     

Generativity and Erikson's “belief in the species”

Generativity is the concern for guiding and promoting the next generation through such creative behavior as parenting, teaching, mentoring, leading, and generating products and outcomes that benefit others. Erikson (1963) has argued that in order to be generative in adulthood, people must have a fundamental “belief in the species” or a faith that human progress is possible and worth working toward. The present study focuses on hope and trust concerning the self and others (Erikson's “belief in the species”). In addition, however, the study examines the relation between generativity and personality traits, in this case, dominance, leadership, self-absorption, and nurturance. A sample of 70 adults was administered (1) a series of self-report questionnaires converging on Erikson's idea of belief in the species, (2) a self-report scale assessing generativity, (3) measures of personality traits, and (4) two open-ended measures of generativity requiring subjects to describe life commitments and creative endeavors. The results provide modest support for Erikson's claim of a link between belief in the species and generativity, with significant positive correlations obtained (1) between self-report generativity and two measures of belief in species and (2) between generativity assessed through life commitments and one measure of belief in the species. In addition, the personality trait of nurturance was positively related to all three generativity measures. Problems and issues in the assessment of generativity are discussed.     

The enduring relevance of Wachtel's “Investigation and its discontents”

Wachtel's [Wachtel, P. L. (1980). Investigation and its discontents: Some constraints on progress in psychological research. American Psychologist, 35, 399–408] essay “Investigation and its discontents” is as relevant today as when first published. Wachtel rightly defends the value of full-time theoretical inquiry, but his concerns about the adverse effects of an emphasis on productivity may be unwarranted.     

Discrimination of “W” and “V” shapes by goldfish

Goldfish were trained to discriminate between “W” and “V” shapes; different groups were trained with the shapes in different orientations. Transfer tests were given after training and the following conclusions were drawn. Animals learned to discriminate between the training shapes by detecting the difference in the number of points present in each; they learned the difference in the relative number of points rather than the absolute number present in each shape; the subjects transferred well to pairs of shapes bearing points facing in different directions from those on the training shapes; knobs were treated as practically equivalent to points; animals relied more heavily on differences at the tops of the shapes than on differences in the bottom halves.     

A comparison between “aware” and “naive” conditions in the suppression of GSR activity

“Aware” (A) and “naive” (N) groups received different instructional sets, the former being informed both of the nature of their task and the response-reinforcement contingency. Negative reinforcement was given to these groups whenever a spontaneous GSR was emitted during four 4-min trial periods. Two corresponding yoked-control groups, CA and CN, received non-contingent reinforcement over the same periods. The contingent reinforcement groups both showed learned suppression of spontaneous GSR activity, but comparison between the A and N groups revealed a significant interaction between Time and Instructional Set. It is suggested that the “aware” instructional set had an inhibitory effect upon learning.     

Amygdala and “emotional” modulation of the relative use of multiple memory systems

The basolateral amygdala modulates the cognitive and habit memory processes mediated by the hippocampus and caudate nucleus, respectively. The present experiments used a plus-maze task that can be acquired using either hippocampus-dependent “place” learning or caudate-dependent “response” learning to examine whether peripheral or intra-basolateral amygdala injection of anxiogenic drugs would bias rats towards the use of a particular memory system. In Experiment 1, adult male Long–Evans rats were trained to swim from the same start point to an escape platform located in a consistent goal arm, and received pre-training peripheral injections of the α₂-adrenoceptor antagonists yohimbine (2.5 or 5.0 mg/kg), RS 79948-197 (0.05, 0.1, or 0.2 mg/kg), or vehicle. On a drug-free probe trial from a novel start point administered 24 h following acquisition, vehicle treated rats predominantly displayed hippocampus-dependent place learning, whereas rats previously treated with yohimbine (2.5, 5.0 mg/kg) or RS 79948-197 (0.1 mg/kg) predominantly displayed caudate-dependent response learning. In Experiment 2, rats receiving pre-training intra-basolateral amygdala infusions of RS 79948-197 (0.1 μg/0.5 μl) also predominantly displayed response learning on a drug-free probe trial. The findings indicate (1) peripheral injections of anxiogenic drugs can influence the relative use of multiple memory systems in a manner that favors caudate-dependent habit learning over hippocampus-dependent cognitive learning, and (2) intra-basolateral amygdala infusion of anxiogenic drugs is sufficient to produce this modulatory influence of emotional state on the use of multiple memory systems.     

The “sexually abused child”: Potential mechanisms of adverse influences of such a label

Labeling and the effects of labeling have been extensively researched in the psychological literature in a variety of different contexts. For example, labeling has been empirically shown to lead to lowered expectancies of behavior and achievement, which can then contribute to the potential for the occurrence of a self-fulfilling prophecy with adverse consequences. Another area that has been extensively researched, with a dramatic increase in the literature base in recent history, is that of child sexual abuse (CSA). Despite various shortcomings of the research literature, the consistent findings have been identification of a variety of negative correlates and symptomatologies associated with CSA. In addition to any direct, negative effects of CSA, there may also be an additional impact from the “label” itself. Although the literature pertaining to CSA and labeling runs deep independently, efforts at addressing the issue of CSA within a labeling contextual framework have been minimal. To that end, this article examines hypothesized mechanisms of how the “sexual abuse” label may potentially have an adverse influence on the children subjected to such a label. The implications of an analysis, which addresses childhood sexual abuse from such a theoretical framework, may be a broader and more holistic understanding of the complexities and sequelae associated with CSA.     

Fast mapping of multiple words: Insights into when “the information provided” does and does not equal “the information perceived”

A candidate process for explaining the rapid vocabulary acquisition during the preschool years is “fast mapping,” children's ability to sketch partial maps of a word's meaning after brief exposure. The present study examines this process for learning multiple words, testing the hypothesis that children's attention to the information critical for quickly mapping multiple words onto their referents depends on the alternatives available when the words are introduced. Fifty-eight 40-month-old children participated in one of two conditions. In both conditions, each trial for novel Word #1 presented a novel object and three familiar ones. The conditions differed in the object choices presented when novel Word #2 was introduced. Although the same information was available to children in both conditions, younger children showed significantly better learning of the new words in the successive condition than in the concurrent condition. Implications of this for age-related differences and for teaching strategies are discussed.     

“Handedness” and skill

The variability of handedness with different tasks is discussed. Experiments are described which show under what conditions handedness becomes evident. Tasks involving three different levels of complexity were used. The simplest task measured the accuracy with which a particular pressure could be reproduced in isometric contraction of the flexors of the index finger on each side in 21 female subjects. In the second situation, the maximum speed of making an attempted tapping movement under the same conditions, was measured in ten of the same subjects using the same muscle group alternating with its antagonists. The same ten subjects were also tested on an aiming task which provided the third level of complexity. The results suggest that differences in performance between the two sides only occur where “timing” or the serial organization of muscle activity is required and that such differences may be due to training.

Whether handedness is inherited or acquired is briefly discussed, and a second series of experiments using the same tasks as before were carried out on one female and nine male subjects. In this instance, the first two tests were used on the big toe of each side as well as the index finger. The results confirm that differences in performance between the two sides on these tasks can be adequately explained in terms of usage or training.

The hypothesis that “timing” is therefore important in the learning of any movement where serial muscle contractions arc involved was tested and confirmed in a third experimental series. The consistency of timing of the application of force in turning a crank handle at maximum speed was measured in five male subjects before and after training. The implications of the results are discussed in relation to other researches on skills.     

The effect of an irrelevant dimension on “same-different” judgements of multi-dimensional stimuli

Subjects made “same”-“different” judgements of simultaneously presented pairs of visual stimuli which could vary either in shape and colour independently, or in shape alone. In both conditions only shape was relevant to the “same”-“different” judgement. In the former condition “same” and “different” reaction times (RTs) were shorter when the states (“same” or “different”) of the relevant and the irrelevant dimension, colour, were the same. This result is interpreted as support for either a perceptual or a response interference hypothesis. The presence of an irrelevant dimension did not appear to affect differentially “same” and “different” judgements. The need for a re-evaluation of the results from other studies of multi-dimensional stimulus discrimination is discussed.     

Why psychology needs conceptual analysts: Wachtel's “discontents” revisited

Commenting on Wachtel's “Investigation and its Discontents” [Wachtel, P. L. (1980). Investigation and its discontents: Some constraints on progress in psychological research. American Psychologist, 35, 399–408], I agree that lack of support for a career path of conceptual analysis and critique is a serious problem. Psychology requires a strong conceptual component because it is subject to unusual distortions and self-deceptions in theory formation and evidential evaluation due to issues of power, self-esteem, and social ideology. I agree with Wachtel that pressures for quantity of publication are detrimental to scientific quality, but dispute his suggestion that excessive focus on quantity in assessing productivity can be addressed by having tenure and promotion candidates submit only their three best papers. Such reviews must be based on the entire record, so improvements must involve journals’ acceptance standards. Regarding Wachtel's concern about the influence of grants on reviews, I argue that grants should be relevant only to the extent they bear on the candidate's scholarly goals.     

The effect of orthographic structure and lexical meaning on “same-different” judgments

Pairs of high frequency English words, orthographically acceptable pseudo-words, and non-word letter strings were presented in a “same”-“different” task. The mean reaction times for “same” judgments were ordered; real words were faster than pseudo-words, and pseudo-words were faster than non-words. The RTs for the “different”, judgments showed no differences among the three types of words, except in the first two days of practice in a blocked presentation condition when the difference between the real words and non-words was marginally significant. These and other results suggest that “same” judgments are based upon a comparison process which efficiently uses higher order semantic and orthographic information in words, whereas “different” judgments are based upon comparison process which performs a self-terminating search of the graphemic information in words. The results were also discussed with reference to hierarchical models of word perception and reading.     

Read but not write “Idea”: Evidence for a third reading mechanism

Most information processing accounts of reading incorporate either two or three mechanisms by which oral reading may be accomplished. The existence of a “third” mechanism by which words may be read lexically but without semantic mediation remains controversial. We report data from a patient (W.T.) with an infarction involving Wernicke's area who was unable to write, repeat, or comprehend words of low imageability yet read these and other words reliably; the patient could not, however, read nonwords. As the patient was unable to read on the basis of sublexical print-to-sound correspondences and, at least for words of low imageability, was unable to read by means of a semantically mediated process, the data from this patient are most readily accommodated by models of reading incorporating three mechanisms.
