Effects of semantic cues on mathematical modeling: Evidence from word-problem solving and equation construction tasks

Mathematical solutions to textbook word problems are correlated with semantic relations between the objects described in the problem texts. In particular, division problems usually involve functionally related objects (e.g., tulips-vases) and rarely involve categorically related objects (e.g., tulips-daisies). We examined whether middle school, high school, and college students use object relations when they solve division word problems (WP) or perform the less familiar task of representing verbal statements with algebraic equations (EQ). Both tasks involved multiplicative comparison statements with either categorically or functionally related objects (e.g., "four times as many cupcakes [commuters] as brownies [automobiles]"). Object relations affected the frequency of correct solutions in the WP task but not in the EQ task. In the latter task, object relations did affect the structure of nonalgebraic equation errors. We argue that students use object relations as "semantic cues" when they engage in the sense-making activity of mathematical modeling.     

Determinants of employee punctuality

Although researchers have studied employee lateness empirically (e.g., S. Adler & J. Golan, 1981; C. W. Clegg, 1983), few have attempted to describe the punctual employee. In the present study, results of a discriminant analysis on employees in Israel indicated that a personality characteristic, time urgency, a subcomponent of Type A behavioral pattern, distinguished between punctual and late employees. Organizational commitment and age of employee's youngest child also distinguished between the groups.     

Effects of sentential context on the processing of unambiguous words by the two cerebral hemispheres

The effect of sentence context on the processing of different aspects of meaning of unambiguous nouns by the two cerebral hemispheres was examined. Participants performed a lexical decision task on target words following two primes, an unambiguous noun preceded by an incomplete sentence. Priming sentences were consistent with either the dominant or the subordinate aspect of meaning of their final unambiguous word. Short and long SOAs were used. A principal finding of this study was that, when compared to unrelated aspects of meaning, for both the short and the long SOAs, the dominant and subordinate aspects of meaning of the unambiguous words were activated regardless of context in both hemispheres. However, the activation of the subordinate aspect of meaning of unambiguous words appears to be more sensitive to sentential context, especially when the unambiguous word is being processed by the left hemisphere.     

How do applicants fake? A response process model of faking on multidimensional forced-choice personality assessments

Faking on personality assessments remains an unsolved issue, raising major concerns regarding their validity and fairness. Although there is a large body of quantitative research investigating the response process of faking on personality assessments, for both rating scales (RS) and multidimensional forced choice (MFC), only a few studies have yet qualitatively investigated the faking cognitions when responding to MFC in a high-stakes context (e.g., Sass et al., 2020). Yet, it could be argued that only when we have a process model that adequately describes the response decisions in high stakes, can we begin to extract valid and useful information from assessments. Thus, this qualitative study investigated the faking cognitions when responding to MFC personality assessment in a high-stakes context. Through cognitive interviews with N = 32 participants, we explored and identified factors influencing the test-takers' decisions regarding specific items and blocks, and factors influencing the willingness to engage in faking in general. Based on these findings, we propose a new response process model of faking forced-choice items, the Activate-Rank-Edit-Submit (A-R-E-S) model. We also make four recommendations for practice of high-stakes assessments using MFC.     

Attachment in Adolescence and Borderline Personality Disorder

Borderline personality disorder (BPD) has been conceptualized as a constellation of symptoms related to problems in self-functioning, emotion regulation, and interpersonal relationships. Its etiology has been connected to individuals’ early childhood environment, caregiving relationships, and traumatic life events. Recent literature has noted the potential presence of BPD beginning in adolescence, or even earlier in childhood. Attachment theory offers a lens for understanding the symptoms of borderline personality disorder and identifying potential aspects of treatment that may be specifically valuable for adolescent patients. Adolescence marks a time when the attachment system has increased relevance due to the importance of identity formation, peer relationships, body representations and the development of autonomy at this time, in the face of physical changes and academic challenges. This article will summarize research on attachment, body representations, personality disorders, and features of development in adolescence, in order to enhance clinical understanding of patients who presenting with these types of difficulties.     

Knowledge junkies or careerbuilders? A mixed-methods approach to exploring the determinants of students' intention to earn a PhD

What are the determinants of students' interest in earning a PhD? In this study, we use a mixed-methods approach to pursue this question. Based on qualitative interview data, we develop a model in which academic motivation and academic achievement interact with contextual factors such as working conditions to influence career intentions. We then test this model using a sample of 229 students currently enrolled in master-level courses of study at a German university. Our results speak to the role of intrinsic versus extrinsic motivations in the context of PhD intentions. In contrast to our expectations, results suggest that while intrinsic life aspirations and the intellectual challenge of gaining a PhD play a significant role for students' intention to pursue a PhD, extrinsic life aspirations and contextual determinants seem to be less influential. Furthermore, results highlight the importance of gaining familiarity and experience with academic work for students' career decisions.     

The effect of age-at-testing on verbal memory among children following severe traumatic brain injury

Memory deficits are a common sequelae following childhood traumatic brain injury (TBI), which often have serious implications on age-related academic skills. The current study examined verbal memory performance using the Rey Auditory Verbal Learning Test (RAVLT) in a pediatric TBI sample. Verbal memory abilities as well as the effect of age at-testing on performance were examined. A sample of 67 children following severe TBI (age average = 12.3 ± 2.74) and 67 matched controls were evaluated using the RAVLT. Age effect at assessment was examined using two age groups: above and below 12 years of age during evaluation. Differences between groups were examined via the 9 RAVLT learning trials and the 7 composite scores conducted out of them. Children following TBI recalled significantly less words than controls on all RAVLT trials and had significantly lower scores on all composite scores. However, all of these scores fell within the low average range. Further analysis revealed significantly lower than average performance among the older children (above 12 years), while scores of the younger children following TBI fell within average limits. To conclude, verbal memory deficits among children following severe TBI demonstrate an age-at-testing effect with more prominent problems occurring above 12 years at the time of evaluation. Yet, age-appropriate performance among children below 12 years of age may not accurately describe memory abilities at younger ages following TBI. It is therefore recommended that clinicians address child’s age at testing and avoid using a single test as an indicator of verbal memory functioning post TBI.     

The Object of One’s Desire: How Perceived Sexual Empowerment Through Objectification is Related to Sexual Outcomes

There is a debate as to whether or not gaining a sense of sexual empowerment through being an object of sexual desire results in empowerment. This debate has been largely theoretical, but there are now operationalizations of self-sexualization, enjoying sexualization, and perceiving sex as a source of personal power which allow for the collection of data on this topic. The current study examined whether these constructs were related to attitudinal and behavioral indicators of sexual satisfaction and sexual agency. An online sample of young, heterosexual, sexually active women was recruited. Our constructs of interest were related to some positive sexual outcomes, including sexual esteem and sexual assertiveness. At the same time, these constructs were related to having faked orgasm, and both self-sexualization and the belief that sex can be a source of power were related to greater frequency of having faked an orgasm. Additionally, none of the variables was significantly related to sexual satisfaction or ease of orgasm. Thus, while there may be some positive sexual outcomes associated with these variables, there are other indicators that a sense of empowerment through objectified sexuality may interfere with true sexual subjectivity.
