Contextual specificity of extinction of delay but not trace eyeblink conditioning in humans

Renewal of an extinguished conditioned response has been demonstrated in humans and in animals using various types of procedures, except renewal of motor learning such as eyeblink conditioning. We tested renewal of delay and trace eyeblink conditioning in a virtual environment in an ABA design. Following acquisition in one context (A, e.g., an airport) and extinction in a different context (B, e.g., a city), tests for renewal took place in the acquisition (A) and extinction context (B), in a counterbalanced order. Results showed renewal of the extinguished conditioned response in the delay but not trace condition.     

Assessing workplace bullying: Spanish validation of a reduced version of the Negative Acts Questionnaire

The aim of the present study was to validate a reduced Spanish version of the Negative Acts Questionnaire (NAQ; Einarsen & Raknes, 1997). This instrument, which has been widely used in various studies, was developed to measure workplace bullying. Two samples, the first comprising 352 employees from 11 organizations, and the second comprising victims of bullying who were recruited from 15 Spanish associations against bullying, participated in the study. Exploratory factor analysis conducted with the data from the first sample revealed a two-factor solution that accounted for 63.3% of the total variance. The data from the second sample were used for confirmatory factor analyses to compare three structure models of the NAQ (one factor, two independent factors, and two correlated factors). The results indicate that the correlated two-factor model provided the best fit to the data (chi2/df = 2.1, CFI = .93, GFI = .95, RMR = .04, RMSEA = .06, AIC = 215.4). Reliability analysis showed that this 14-item Spanish version had high internal consistency. Significant correlations between the NAQ and its dimensions and diverse health and perceived stress scales were found, which provided evidence of construct validity. Taken conjointly, the results of this study support the use of the Spanish version of the reduced NAQ in future research.     

Task Specificity in the Use of Words in Mathematics: Evidence from Bilingual Problem Solvers

Mathematics is often said to be a different language in itself. Three experiments were conducted to show some evidence for this common notion. It was hypothesized that in math word problem solving, people interpret words like “more” and “less” in specialized ways that are specific to the task of math word problem solving. Subjects were given texts with quantitative information, but the texts were framed either as math problems or as stories, and were written either in English or Filipino. Subjects were then asked to verify statements that describe quantitative relations given in the text; these relations either stated an exact or an inexact quantitative difference. The verification responses and verification times in three experiments show that subjects more often accepted the inexact difference as true when the text was framed as a story compared to when framed as a problem. These results support the hypothesis that the use of the specialized meaning is specific to the task of solving word problems in math. The data were equivocal about the role of the language used in the operation of this knowledge. The results were discussed in terms of the implications of specificity of knowledge, context sensitivity, and the possible role of language use in the process of learning and developing mathematical knowledge.     

Using Rebt and Supportive Psychotherapy with Post-Stroke Patients

This paper discusses the benefits of using Calabro's (1990) three-stage cognitive-behavioral model, to determine when to use supportive Psychotherapy or Rational-Emotive Behavior Therapy (REBT) with post-stroke patients. It also discusses the benefits of using a support group and how to decide when to use a group and/or individual psychotherapy.     

Comparing implicit and explicit attitudes of gay,straight, and non-monosexual groups toward transmen and transwomen

Background: Transphobia studies have typically relied on self-report measures from heterosexual samples. However, there is evidence suggesting the need to use indirect measures and to explore transphobia among other populations. Aims: This study examined how explicit and implicit attitudes toward transwomen and transmen differ between people of different sexual orientations. Methods: Cisgender participants (N = 265) completed measures of explicit feelings toward transmen and transwomen, as well as Implicit Association Tests (IAT) for each group. Comparisons were made between 54 gay, 79 straight, and 132 non-monosexual (asexual, bisexual, pansexual) individuals. Results: An interaction was found between measurement type (explicit, implicit) and sexual orientation (straight, gay, non-monosexual). With regard to transmen, gay respondents’ explicit and implicit scores diverged such that they explicitly reported lower bias than their straight counterparts, but their Transmen-IAT showed an implicit preference for biological men over transmen. For attitudes toward transwomen, implicit measurement scores were consistently negative and did not differ by group. Gay participants also reported positive explicit attitudes toward transwomen, similar to non-monosexual people. Discussion: Overall, findings show that gay people tend to report positive attitudes toward transgender people explicitly, but tend to have implicit bias against both transmen and transwomen. Future studies need to explore the origins of these biases and how they relate to the complex interplay of sex, gender, and sexual orientation.     

Language and modeling word problems in mathematics among bilinguals

The study was conducted to determine whether the language of math word problems would affect how Filipino-English bilingual problem solvers would model the structure of these word problems. Modeling the problem structure was studied using the problem-completion paradigm, which involves presenting problems without the question. The paradigm assumes that problem solvers can infer the appropriate question of a word problem if they correctly grasp its problem structure. Arithmetic word problems in Filipino and English were given to bilingual students, some of whom had Filipino as a first language and others who had English as a first language. The problem-completion data and solution data showed similar results. The language of the problem had no effect on problem-structure modeling. The results were discussed in relation to a more circumscribed view about the role of language in word problem solving among bilinguals. In particular, the results of the present study showed that linguistic factors do not affect the more mathematically abstract components of word problem solving, although they may affect the other components such as those related to reading comprehension and understanding.     

The capacity of visual short-term memory is set both by visual information load and by number of objects

Previous research has suggested that visual short-term memory has a fixed capacity of about four objects. However, we found that capacity varied substantially across the five stimulus classes we examined, ranging from 1.6 for shaded cubes to 4.4 for colors (estimated using a change detection task). We also estimated the information load per item in each class, using visual search rate. The changes we measured in memory capacity across classes were almost exactly mirrored by changes in the opposite direction in visual search rate (r2=.992 between search rate and the reciprocal of memory capacity). The greater the information load of each item in a stimulus class (as indicated by a slower search rate), the fewer items from that class one can hold in memory. Extrapolating this linear relationship reveals that there is also an upper bound on capacity of approximately four or five objects. Thus, both the visual information load and number of objects impose capacity limits on visual short-term memory.     

Type a and Risk Taking in Everyday Money Matters

The purpose of the present study is to extend previous research investigating personality factors as determinants of financial risk taking in everyday money matters (e.g., personal investments and household affairs). Type A and Type B subjects were asked to make a series of everyday financial decisions that varied in degree of risk. Type A individuals took greater financial risks than Type B individuals. The results provide additional support for the influence of personality factors in everyday financial risk-taking behavior and demonstrated another area of risk taking associated with the Type A behavior pattern not previously identified.
