Explaining the price-volume relationship: The difference between price changes and changing prices

Trading on the stock market increases when there are large changes in price levels, and falls when these changes are small. An experimental test revealed strong support for the hypothesis that large price changes cause heavy trading. Trading patterns, profit data, and memory measures revealed that the vast majority of the subjects employed a tracking strategy; that is, they bought when the price fell and sold when it rose. To test whether the use of this strategy was due to a selective application of the representativeness heuristic on the price stimuli, a second experiment was conducted in which subjects were presented either with only price information or with only price change information. Results supported the representativeness hypothesis, with subjects in the price change condition tracking poorly and earning less profit. The results are discussed with regard to their implications for the stock market and the psychology of prediction.     

Personal and socio-economic variables in relation with attitudes towards planned family

The study purpose was to examine the relationships between various personal, demographic and socioeconomic variables and attitude towards family planning on a large sample. The sample included 300 cases, representing urban and rural and male and female compositions of the population of Agra District. The Attitude Towards Family Planning (ATFP) Scale by Kapoor (1973) was used to assess the attitudes toward family planning. Age had no relationship with attitude towards family planning but education and income had substantial positive relationships (r=.56 and .40, respectively, significant at .01 level), followed by occupation showing the higher the socioeconomic status of the respondent the more favorable the attitude. Family size was found to be inversely related with attitude, indicating respondents having more children may not have favorable attitudes. This was more the case with the female sex of the child.     

Beat them or ban them: the characteristics and social functions of anger and contempt

This article reports 3 studies in which the authors examined (a) the distinctive characteristics of anger and contempt responses and (b) the interpersonal causes and effects of both emotions. In the 1st study, the authors examined the distinction between the 2 emotions; in the 2nd study, the authors tested whether contempt could be predicted from previous anger incidents with the same person; and in the 3rd study, the authors examined the effects of type of relationship on anger and contempt reactions. The results of the 3 studies show that anger and contempt often occur together but that there are clear distinctions between the 2 emotions: Anger is characterized more by short-term attack responses but long-term reconciliation, whereas contempt is characterized by rejection and social exclusion of the other person, both in the short-term and in the long-term. The authors also found that contempt may develop out of previously experienced anger and that a lack of intimacy with and perceived control over the behavior of the other person, as well as negative dispositional attributions about the other person, predicted the emergence of contempt.     

Personal meaning and ethics in engineering

The study of engineering ethics tends to emphasize professional codes of ethics and, to lesser degrees, business ethics and technology studies. These are all important vantage points, but they neglect personal moral commitments, as well as personal aesthetic, religious, and other values that are not mandatory for all members of engineering. This paper illustrates how personal moral commitments motivate, guide, and give meaning to the work of engineers, contributing to both self-fulfillment and public goods. It also explores some general frameworks for thinking about these commitments and calls for further exploration of them.     

Coping with rising food costs in a closed economy: feeding behavior and nocturnal hypothermia in pigeons.

The pigeon's response to increasing fixed-ratio schedules in a 24-hr closed economy is marked by changes in feeding behavior during the daily light phase and by changes in body temperature during the dark phase. The time course of these responses to increasing behavioral cost of obtaining food is very different. Feeding is most affected immediately, within the first day of exposure to moderate fixed ratios. The number of times the pigeons produce the food hopper each day decreases, and the rate at which they eat from the food hopper (grams per minute) when it is available increases, as the fixed ratio is raised. Body temperature is affected later, falling to progressively lower resting levels during the dark phase as body weight drops at the higher fixed ratios when food intake is reduced. The changes in feeding and in body temperature that occur as the fixed-ratio schedule increases seem to reduce daily energy expenditures, within the constraints imposed by the experiment. The ascending and descending limbs of the bitonic function obtained when total daily operant responding is plotted as a function of fixed-ratio schedule in the closed economy is possibly related to the occurrence of thermoregulatory strategies for energy conservation. The energetic analysis of performances in the closed economy requires consideration of a variety of energetic strategies available to the species being studied.     

Goals and responses to failure: Knowing when to hold them and when to fold them

The ability to disengage from hopeless situations is critical to goal attainment and effective self-regulation. Two experiments investigated the effects of striving to attain success (approach goals) versus striving to avoid failure (avoidance goals) on persistence. Participants completed anagrams designed so that less persistence during an initial set of unsolvable anagrams was beneficial. In Study 1, participants reported how motivated they were by approach and avoidance goals. In Study 2, participants were primed to set approach or avoidance goals. Participants with avoidance goals persisted longer during failure, with more intense and enduring emotional distress, than those with approach goals. Greater anger predicted spending more time on subsequent unsolvable anagrams and accounted for differences in persistence. The results suggest that people with approach goals are better able to identify when they should disengage during failure, and disengage more completely, than people with avoidance goals. An earlier version of this article was presented at the Society for Personality and Social Psychology conference, Palm Springs, CA, January, 2006.     

It’s one thing to rule them all and another thing to bind them

In this paper we offer a response to one argument in favour of Priority Monism, what Jonathan Schaffer calls the nomic argument for monism. We proceed in three stages. We begin by introducing Jonathan Schaffer’s Priority Monism and the nomic argument for that view. We then consider a response to the nomic argument that we presented in an earlier paper (Baron and Tallant in Philos Phenomenol Res 93:583–606, 2016). We show that this argument suffers from a flaw. We then go on to offer a different response to the nomic argument. The core idea is that the current laws of physics are not integrated in the manner that Schaffer requires to get the nomic argument for monism off the ground.

     

Confidence in Personal Preferences

The first aim of this study was to test the self‐consistency model (SCM) of subjective confidence as it applies to personal preferences. According to SCM, participants presented with a two‐alternative forced‐choice (2AFC) item draw a small sample of representations of the item. Their confidence reflects the extent to which the choice is representative of the population of representations associated with the item, and the likelihood of making that choice on subsequent occasions. The second aim was to use confidence judgment as a clue to the dynamics of online preference construction. Participants were presented with 2AFC items measuring everyday personal preferences. The task was presented five times. In line with SCM, (i) when participants changed their preferences across presentations, they were systematically more confident when they made their more frequent choice; (ii) confidence in a choice in the item's first presentation predicted the likelihood of repeating that choice in subsequent presentations; (iii) despite the idiosyncratic nature of personal preferences, confidence was higher for consensual than for nonconsensual preferences; (iv) when participants predicted the preferences of others, they were also more confident when their predictions agreed with those of others; and (v) the confidence/accuracy correlation for predictions was positive for consensually correct but negative for consensually wrong predictions. These results suggest that confidence in preferences can help separate between the stable and variable contributions to preference construction in terms of the population of representations available in memory and the representations that are accessible at the time of preference solicitation, respectively.

Personal and community sustainability

Many community members reduce their community involvements as they more through midlife. This may be true for community psychologists as well. Yet research evidence suggests that-intellectually, at least-we can function at or near peak levels through our 80s and 90s. How then might we best sustain ourselves and our work through our entire lives? Answers may lie in full exercise of all capacities, in strong support networks, and in actions that meet one's deeper needs, “the needs of the soul”. These same principles may sustain community life as well, for some key principles of personal and community sustainability may be similar. Applications of these ideas to communities and to community psychology are discussed.
