Persisting effect of prior experience of change blindness

Most cognitive scientists know that an airplane tends to lose its engine when the display is flickering. How does such prior experience influence visual search? We recorded eye movements made by vision researchers while they were actively performing a change-detection task. In selected trials, we presented Rensink's familiar 'airplane' display, but with changes occurring at locations other than the jet engine. The observers immediately noticed that there was no change in the location where the engine had changed in the previous change-blindness demonstration. Nevertheless, eye-movement analyses indicated that the observers were compelled to look at the location of the unchanged engine. These results demonstrate the powerful effect of prior experience on eye movements, even when the observers are aware of the futility of doing so.     

Illocutionary Silencing

Rae Langton and Jennifer Hornsby have argued that pornography might create a climate whereby a woman's ability to refuse sex is literally silenced or removed. Their central argument is that a failure of 'uptake' of the woman's intention means that the illocutionary speech act of refusal has not taken place. In this paper, I challenge the claims from the Austinian philosophy of language which feature in this argument. I argue that uptake is not in general required for illocution, nor is it required for refusal in particular. I conclude with remarks on the relationship between illocutionary and perlocutionary speech-acts.     

Ongoing change in psychoanalytic theory implications for analysis of religious experience

Hans Loewald (1980) once made the distinction between ghosts and ancestors, the former always wanting to return to the land of the living, the latter being able to rest in peace and live forth through their progeny in the present generation. Extending this metaphor, Stephen Mitchell (1991) has noted that the intellectual integrity and vitality of psychoanalysis depends on our shifting our view of Freud from an unburied ghost who haunts us to an honored ancestor. I argue that perhaps nowhere is Freud's enduring presence greater than in psychoanalytic perspectives on religion, and it is often as an unburied ghost. Ongoing change in psychoanalytic theory, however, affords respectful amendment to his work in a way that allows Freud to be a dearly honored ancestor from whom we are all psychoanalytic descendents. Three developments in psychoanalytic theory have special implication for the analysis of religious experience. These areas of change pertain to contemporary understanding of illusion, narrative, and social constructivism. I offer in conclusion seven points for further consideration.     

Science education,conceptual change and breaking with everyday experience

Science educators and those who investigate science learning have tended, for good reason, to focus their attention on students' conceptual development, Such a focus is, however, too narrow to provide full and proper understanding of the complexities of original science learning. Recently developmental cognitive psychologists have called on the work of postpositivistic philosophers of science, especially Thomas Kuhn, to bolster their research into conceptual development in science acquisition. What these psychologists have not recognized is that Kuhn's position is actually a derivative of Wittgenstein's methodological nominalism, a viewpoint far more favorable to behaviorism than cognitive psychology. After drawing out some of the consequences of this fact for the developmental cognitive psychologist program for studying science learning, we suggest our own radical alternative. Drawing on Floden, Buchmann and Schwille's idea of Breaking with Everyday Experience we propose an alternative notion of original science learning in terms of Alfred Schutz's modification of Williams James' many worlds thesis. The many worlds thesis will allow us to better understand students' difficulty in learning idealized worlds such as science, worlds that represent a discontinuous break with ordinary everyday practical experience.     

Decisions from experience: How groups and individuals adapt to change

Whether groups make better judgments and decisions than individuals has been studied extensively, but most of this research has focused on static tasks. How do groups and individuals compare in settings where the decision environment changes unexpectedly and without notification? This article examines group and individual behavior in decisions from experience where the underlying probabilities change after some trials. Consistent with the previous literature, the results showed that groups performed better than the average individual while the decision task was stable. However, group performance was no longer superior after a change in the decision environment. Group performance was closer to the benchmark of Bayesian updating, which assumed perfect memory. Findings suggest that groups did not adopt decision routines that might have delayed their adaption to change in the environment. Rather, they seem to have coordinated their responses, which led them to behave as if they had better memory and subsequently delayed adaptation.     

Color preferences change after experience with liked/disliked colored objects

How are color preferences formed, and can they be changed by affective experiences with correspondingly colored objects? We examined these questions by testing whether affectively polarized experiences with images of colored objects would cause changes in color preferences. Such changes are implied by the ecological valence theory (EVT), which posits that color preferences are determined by people’s average affective responses to correspondingly colored objects (Palmer & Schloss, Proceedings of the National Academy of Sciences, 107, 8877–8882, 2010). Seeing images of strongly liked (and disliked) red and green objects, therefore, should lead to increased (and decreased) preferences for correspondingly colored red and green color patches. Experiment 1 showed that this crossover interaction did occur, but only if participants were required to evaluate their preferences for the colored objects when they saw them. Experiment 2 showed that these overall changes decreased substantially over a 24-h delay, but the degree to which the effect lasted for individuals covaried with the magnitude of the effects immediately after object exposure. Experiment 3 demonstrated a similar, but weaker, effect of affectively biased changes in color preferences when participants did not see, but only imagined, the colored objects. The overall pattern of results indicated that color preferences are not fixed, but rather are shaped by affective experiences with colored objects. Possible explanations for the observed changes in color preferences were considered in terms of associative learning through evaluative conditioning and/or priming of prior knowledge in memory.     

A Partial Defense of Illocutionary Silencing

Catharine MacKinnon has pioneered a new brand of anti‐pornography argument. In particular, MacKinnon claims that pornography silences women in a way that violates their right to free speech. In what follows, we focus on a certain account of silencing put forward by Jennifer Hornsby and Rae Langton, and we defend that account against two important objections. The first objection contends that this account makes a crucial but false assumption about the necessary role of hearer recognition in successful speech acts. In response, we argue that, as silencing primarily concerns communication, Hornsby and Langton are perfectly correct to treat hearer recognition as they do. The second objection contends that their particular account of silencing has the unacceptable result of undermining the responsibility of rapists. We here argue that no such result follows from their account.     

Silencing the self in college settings and adjustment

The correlations among several measures of silencing the self and scores on the College Adjustment Scale were assessed for male and female students at a midwestern university (N = 143). Analysis showed that high scores on Jack's 1991 Silencing the Self Scale and on one of three new measures designed to extend silencing the self to social group settings were associated with scores indicating poorer college adjustment. Also, men scored higher than women on Jack's 1991 measure, and no significant interactions were found for sex and adjustment for any of the silencing the self measures. Thus, silencing the self was generally associated with poorer adjustment scores and similarly for both women and men.     

Effect of visual experience on iocational judgements after perspective change in small-scale space

Congenitally blind, late blind and blindfold sighted adults overleamed an object-array within a square frame by touch, and judged, facing the midpoint of the frame, the near/far/left/right locations of objects from sides and diagonally from corners. One-half were first guided to points (A-condition), the rest were first asked to imagine themselves as being at points (I-condition). Group and condition did not, but group and observation point did, interact. Lack of visual experience added to RTs and total times and increased errors especially at diagonal stations. Congenitally blind subjects differed from both late blind and blindfold sighted subjects. However, a section of the congenitally blind subjects attained the level of blindfold sighted subjects. The sequence A-I speeded up judgements in all groups. Group did not interact with size of space. Congenitally blind subjects reportedly resorted to holistic representations, but had specific limitations in using them at diagonal stations. Orientation skills of the congenitally blind in far space could be improved by practising perspective taking in near space.     

Sustained attention can create an (illusory) experience of seeing dynamic change

Recent studies speculated that two types of change detection exist, one involving the experience of seeing dynamic change (change over brief interval), the other involving detecting a completed change (change over long interval), with only the former requiring sustained attention. To examine this supposition, a flicker change detection task was conducted in which the spatial location of objects was manipulated (shift, no-shift). In shift conditions, changed image display appeared in different locations than they did in the original display. The time interval separating images was manipulated (200 or 1000 ms). Results showed that a shift led to poor change detection only in the short interval condition. The performance decline by the image shift was not attenuated even when participants knew beforehand whether or not a shift would occur. Results indicate that sustained attention, which is sustained for a brief time, is related to the experience of seeing dynamic change.     

Openness to experience, identity flexibility, and life change in adults

The personality trait of openness to experience was used to predict identity flexibility, the tendency of adults to evaluate alternative identity commitments in the area of family and work. Openness to experience was also used as an independent variable to predict the occurrence of actual life change 12 months after identity flexibility was ascertained. A sample of 57 adults (34 women and 23 men) ranging in age from 24 to 61 (M = 41 years) was tested twice over the 12-month period. Age and openness to experience significantly predicted identity flexibility, whereas only years of education predicted life change. Identity flexibility was significantly related to life change. It was concluded that both personality and perceived and actual social resources are predictors of flexibility and life change in adulthood.     

Gender Differences in the Construct Validity of the Silencing the Self Scale

Gender differences in the construct validity of Jack's (1991) Silencing the Self Scale (STSS) were assessed using 187 female and 169 male undergraduates. Results of exploratory and confirmatory factor analyses revealed gender differences in the scale's latent structure and at best provided only limited support for the validity of the scale's four subscales for women. Among men, the studies exposed a weakness in the scale's construct validity and provided insights into possible alternative interpretations made by men when responding to the scale's items. Convergent and discriminant validity of the scale were assessed by correlating it with measures of neuroticism and attachment. Whereas the construct validity of the STSS for use with women was supported, evidence was weaker for men. For men, data suggest that the STSS, in part, taps a motive to avoid intimacy and relationship situations that limit one's sense of independence and autonomy, a construct incongruous with Jack's notion of self-silencing.     

On Silencing and Systematicity: The Challenge of the Drowning Case

Silencing is a speech‐related harm. We here focus on one particular account of silencing offered by Jennifer Hornsby and Rae Langton. According to this account, silencing is systematically generated, illocutionary‐communicative failure (of a very specific sort). We here raise an apparent challenge to that account. In particular, we offer an example—the drowning case—that meets these conditions of silencing but does not intuitively seem to be an instance of it. First, we explore several conditions one might add to the Hornsby‐Langton account, but we argue that none are satisfactory. Then, we further explore the systematicity condition, which is insufficiently characterized in the current literature. Although we explore several promising ways to further characterize this condition, we ultimately conclude that more work needs to be done. Consequently, because this systematicity condition is under‐specified, the Hornsby‐Langton account of silencing is incomplete.     

It's never too late to change: A group psychotherapy experience for older women

Group psychotherapy in a mixed gender group is seen as useful for treatment of the unique existential and emotional problems of the older woman. This article describes the first year of a psychotherapy group for older adults, four women and three men in their early fifties to late sixties. Some issues discussed unique to this age group were loss, isolation, changing body image, and changed political views. There were differences in reactions between the men and women. The major value of group psychotherapy for older women is seen as providing a safe arena for exploring current issues, integrating a sense of self, enhancing self-worth, and overcoming isolation and despair.     

Tracking Epistemic Violence,Tracking Practices of Silencing

Too often, identifying practices of silencing is a seemingly impossible exercise. Here I claim that attempting to give a conceptual reading of the epistemic violence present when silencing occurs can help distinguish the different ways members of oppressed groups are silenced with respect to testimony. I offer an account of epistemic violence as the failure, owing to pernicious ignorance, of hearers to meet the vulnerabilities of speakers in linguistic exchanges. Ultimately, I illustrate that by focusing on the ways in which hearers fail to meet speaker dependency in a linguistic exchange, efforts can be made to demarcate the different types of silencing people face when attempting to testify from oppressed positions in society.     

The dynamic change of self-efficacy in information searching on the Internet: influence of valence of experience and prior self-efficacy

The authors investigated the dynamic change of specific self-efficacy in information searching on the Internet. In Study 1, the valence of experience was manipulated by task difficulty to obtain the developmental curve of self-efficacy change in consecutive information-searching trials. The results indicated that positive task experiences in information searching elicited a linear increase in self-efficacy. In contrast, negative task experiences elicited a more rapid decrease in self-efficacy. Self-efficacy of participants decreased to a lower level after the first negative experience and displayed a quadratic trend toward a floor effect. In Study 2, the authors examined the moderating effect of initial self-efficacy on the valence of experience. The enhancement effect of positive task experience on self-efficacy was more pronounced for individuals with lower levels of self-efficacy, whereas the deteriorating effect of negative experience was more prominent for individuals with higher levels of self-efficacy.
