Neighborhood effects in visual word recognition: Facilitatory or inhibitory?

In five experiments, in which subjects were to identify a target word as it was gradually clarified, we manipulated the target's frequency of occurrence in the language and its neighborhood size—the number of words that can be constructed from a target word by changing one letter, while preserving letter position. In Experiments 1–4, visual identification performance to screen-fragmented words was measured. In Experiments 1 and 2, we used the ascending method of limits, whereas Experiments 3 and 4 presented a fixed-level fragment. In Experiment 1, there was no relation between overall accuracy and neighborhood size for-words-between three and six letters in length. However, more errors of commission (guesses) were made for high-neighborhood words and more errors of omission (blanks) were made for low-neighborhood words. Letter errors within guesses occurred at serial positions having many neighbors, and these positions were also likely to contain consonants rather than vowels. In Experiment 2, a smallfacilitatory effect of neighborhood size on bothhigh- and low-frequency words was found. In contrast, in Experiments 3 and 4, using the same set of words,inhibitory effects of neighborhood size, but only for low-frequency words, were found. Experiment 5, using a speeded identification task, showed results parallel to those of Experiments 3 and 4. We suggest that whether neighborhood effects are facilitatory or inhibitory depends on whether feedback allows subjects to disconfirm initial hypotheses that the target is a high-frequency neighbor.     

Role of psychocultural factors in the adjustment of Soviet Jewish refugees: Applying Kleinian theory of mourning

The purpose of this paper is to show how failures of adjustment of Soviet refugees to America are to a great degree determined by their difficulties in mourning. The author argues that due to such difficulties, Soviet refugees may get fixated sometimes for long periods of time at different stages of the mourning process. Such fixations may be the causes for peculiar types of behavior, frequently exhibited by these refugees in America and attributed by various authors to their psychocultural characteristics. Melanie Klein's analysis of mourning and its relationship to manic depressive states is applied to understand the mourning process in this population. The author shows that difficulties in the mourning process experienced by Soviet refugees may be connected with the culturally acquired inhibitions of mourning. Such inhibitions are analyzed from a family, historical and cultural perspective.     

Reasoning strategies with rational numbers revealed by eye tracking

Recent research has begun to investigate the impact of different formats for rational numbers on the processes by which people make relational judgments about quantitative relations. DeWolf, Bassok, and Holyoak (Journal of Experimental Psychology: General, 144(1), 127–150, 2015) found that accuracy on a relation identification task was highest when fractions were presented with countable sets, whereas accuracy was relatively low for all conditions where decimals were presented. However, it is unclear what processing strategies underlie these disparities in accuracy. We report an experiment that used eye-tracking methods to externalize the strategies that are evoked by different types of rational numbers for different types of quantities (discrete vs. continuous). Results showed that eye-movement behavior during the task was jointly determined by image and number format. Discrete images elicited a counting strategy for both fractions and decimals, but this strategy led to higher accuracy only for fractions. Continuous images encouraged magnitude estimation and comparison, but to a greater degree for decimals than fractions. This strategy led to decreased accuracy for both number formats. By analyzing participants’ eye movements when they viewed a relational context and made decisions, we were able to obtain an externalized representation of the strategic choices evoked by different ontological types of entities and different types of rational numbers. Our findings using eye-tracking measures enable us to go beyond previous studies based on accuracy data alone, demonstrating that quantitative properties of images and the different formats for rational numbers jointly influence strategies that generate eye-movement behavior.     

Women's Physiological Reactions to Physically Demanding Work

Eight females ( age = 20 yrs.) were subjects in an experiment consisting of two parts. The first part measured the maximal work capacity and peak work load on a treadmill at a speed of 8 kms (5 mph) with grade increasing 2 1/2% every 3 minutes. The second part measured energy expended on a treadmill walked under varying conditions of speed, grade, and load in an eight hour day of strenuous work. The results showed that these women were able to do strenuous work expending 2369 kcals for 8 1/2 hours. The energy expended exceeded that required for most physically demanding occupations. The results have implications for vocational choice research for women who have been excluded from occupations due to an assumed lack of strength.     

An Accuracy Based Approach to Higher Order Evidence

The aim of this paper is to apply the accuracy based approach to epistemology to the case of higher order evidence: evidence that bears on the rationality of one's beliefs. I proceed in two stages. First, I show that the accuracy based framework that is standardly used to motivate rational requirements supports steadfastness—a position according to which higher order evidence should have no impact on one's doxastic attitudes towards first order propositions. The argument for this will require a generalization of an important result by Greaves and Wallace for the claim that conditionalization maximizes expected accuracy. The generalization I provide will, among other things, allow us to apply the result to cases of self‐locating evidence. In the second stage, I develop an alternative framework. Very roughly, what distinguishes the traditional approach from the alternative one is that, on the traditional picture, we're interested in evaluating the expected accuracy of conforming to an update procedure. On the alternative picture that I develop, instead of considering how good an update procedure is as a plan to conform to, we consider how good it is as a plan to make. I show how, given the use of strictly proper scoring rules, the alternative picture vindicates calibrationism: a view according to which higher order evidence should have a significant impact on our beliefs. I conclude with some thoughts about why higher order evidence poses a serious challenge for standard ways of thinking about rationality.     

Women outperform men in distinguishing between authentic and nonauthentic smiles

Women tend to be more accurate in decoding facial expressions than men. We hypothesized that women’s better performance in decoding facial expressions extends to distinguishing between authentic and nonauthentic smiles. We showed participants portrait photos of persons who smiled because either they saw a pleasant picture (authentic smile) or were instructed to smile by the experimenter (nonauthentic smile) and asked them to identify the smiles. Participants judged single photos of persons depicting either an authentic or a nonauthentic smile, and they judged adjacent photos of the same person depicting an authentic smile and a nonauthentic smile. Women outperformed men in identifying the smiles when judging the adjacent photos. We discuss implications for judging smile authenticity in real life and limitations for the observed sex difference.     

Religious orientation and coping with cancer

In this study we investigated the role of religious orientation in coping with stresses associated with cancer. A measure of daily coping and the Religious Orientation scale were administered to forty hematology-oncology patients in order to examine frequency of eight coping responses across religious orientations. It was found that proreligious and intrinsic participants used religion significantly more often than nonreligious and extrinsic types to cope with stresses associated with their cancer. We concluded that religious orientation and commitment influence the coping process, and suggest that religious commitment be included in studies of coping with cancer.     

Internalism without Luminosity1

Internalists face the following challenge: what is it about an agent's internal states that explains why only these states can play whatever role the internalist thinks these states are playing?  Internalists have frequently appealed to a special kind of epistemic access that we have to these states. But such claims have been challenged on both empirical and philosophical grounds.  I will argue that internalists needn't appeal to any kind of privileged access claims.  Rather, internalist conditions are important because of the way in which we expect them to act as causal mediators between states of the world, on the one hand, and our beliefs and actions on the other.
