Task effects reveal cognitive flexibility responding to frequency and predictability: Evidence from eye movements in reading and proofreading

It is well-known that word frequency and predictability affect processing time. These effects change magnitude across tasks, but studies testing this use tasks with different response types (e.g., lexical decision, naming, and fixation time during reading; Schilling, Rayner, & Chumbley, 1998), preventing direct comparison. Recently, Kaakinen and Hyönä (2010) overcame this problem, comparing fixation times in reading for comprehension and proofreading, showing that the frequency effect was larger in proofreading than in reading. This result could be explained by readers exhibiting substantial cognitive flexibility, and qualitatively changing how they process words in the proofreading task in a way that magnifies effects of word frequency. Alternatively, readers may not change word processing so dramatically, and instead may perform more careful identification generally, increasing the magnitude of many word processing effects (e.g., both frequency and predictability). We tested these possibilities with two experiments: subjects read for comprehension and then proofread for spelling errors (letter transpositions) that produce nonwords (e.g., trcak for track as in Kaakinen & Hyönä) or that produce real but unintended words (e.g., trial for trail) to compare how the task changes these effects. Replicating Kaakinen and Hyönä, frequency effects increased during proofreading. However, predictability effects only increased when integration with the sentence context was necessary to detect errors (i.e., when spelling errors produced words that were inappropriate in the sentence; trial for trail). The results suggest that readers adopt sophisticated word processing strategies to accommodate task demands.     

Religious Tradition,Religiosity, or Everyday Theologies? Unpacking Religion’s Relationship to Support for Legalizing Same-Sex Marriage Among a College Student Sample

This study explores the differential impact of religious tradition, religiosity, and everyday theologies on support for legalizing same-sex marriage among a sample of undergraduate college students. The findings suggest that among college students in the United States the group of everyday theologies—personal religious beliefs that emerge through individuals’ lived experiences and social interactions—that we examine has a larger influence on attitudes about legalizing same-sex marriage than do either religious tradition or religiosity (measured as attendance, prayer, and guidance). We operationalize the concept of everyday theologies as levels of endorsement for six different religious themes. Implications for social movements promoting same-sex marriage and future research are discussed.     

Psychopaths and blame: The argument from content

The recent debate over the moral responsibility of psychopaths has centered on whether, or in what sense, they understand moral requirements. In this paper, I argue that even if they do understand what morality requires, the content of their actions is not of the right kind to justify full-blown blame. I advance two independent justifications of this claim. First, I argue that if the psychopath comes to know what morality requires via a route that does not involve a proper appreciation of what it means to cause another harm or distress, the content of violations of rules against harm will be of a lower grade than the content of similar actions by normal individuals. Second, I argue that in order to intend a harm to a person—that is, to intend the distinctive kind of harm that can only befall a person—it is necessary to understand what personhood is and what makes it valuable. The psychopath's deficits with regard to mental time travel ensure that s/he cannot intend this kind of harm.     

The time course of episodic associative retrieval: Electrophysiological correlates of cued recall of unimodal and crossmodal pair-associate learning

Little is known about the time course of processes supporting episodic cued recall. To examine these processes, we recorded event-related scalp electrical potentials during episodic cued recall following pair-associate learning of unimodal object-picture pairs and crossmodal object-picture and sound pairs. Successful cued recall of unimodal associates was characterized by markedly early scalp potential differences over frontal areas, while cued recall of both unimodal and crossmodal associates were reflected by subsequent differences recorded over frontal and parietal areas. Notably, unimodal cued recall success divergences over frontal areas were apparent in a time window generally assumed to reflect the operation of familiarity but not recollection processes, raising the possibility that retrieval success effects in that temporal window may reflect additional mnemonic processes beyond familiarity. Furthermore, parietal scalp potential recall success differences, which did not distinguish between crossmodal and unimodal tasks, seemingly support attentional or buffer accounts of posterior parietal mnemonic function but appear to constrain signal accumulation, expectation, or representational accounts.     

Personal Growth of Mothers of Preterms: Objective Severity of the Event,Subjective Stress,Personal Resources,and Maternal Emotional Support

This prospective study investigated the personal growth of Israeli mothers of premature babies at two medically defined risk levels (infants at low risk, n = 42; infants at moderate-high risk, n = 52), examining the contribution to the five dimensions of personal growth of objective event characteristics (baby’s risk level), perceived levels of mother’s stress (linear and curvilinear associations), and mother’s personal resources (self-esteem, attachment styles, perceived emotional support from her own mother). In addition, the role of the event severity as a moderator of the association between perceived maternal emotional support and personal growth was explored. Findings indicate that mothers in the two risk groups did not differ in level of perceived stress. Mothers of infants at moderate-high risk, however, experienced more spiritual change. In addition, consistent curvilinear associations emerged between perceived levels of stress and personal growth for three dimensions of growth: new possibilities, personal strength, and relations with others (with a similar trend for appreciation of life). Thus, mothers reporting moderate stress levels experienced the highest personal growth. Finally, risk group played a moderating role in the association between perceived maternal emotional support and personal growth on the dimensions of new possibilities, personal strength, and relations with others. On these dimensions, only among mothers of low-risk babies were higher levels of maternal emotional support associated with greater personal growth. The results highlight the importance of the subjective experience and the value of maternal emotional support for the personal growth of mothers of preterms. These findings may help in designing measures to identify populations at risk and developing appropriate interventions, as well as impact on the working procedures and support currently offered in most neonatal intensive care units.     

Using Small-Group Instruction to Improve Students' Reading Fluency: An Evaluation of the Existing Research

Reading fluency is necessary for reading comprehension, but approximately 40% of U.S. fourth-grade students have inadequate reading fluency skills. Because small-group (SG) instruction is often used as a first line of intervention for struggling readers, SG instruction targeting deficiencies in text reading fluency ought to be part of every school's intervention toolbox. The authors summarize the existing research on instruction and interventions that specifically targets reading fluency and is implemented by an adult with 3 or more students at once. Key findings revealed that most studies used a single-case design, nearly all studies were rated positively in terms of methodological quality, and the majority of participants significantly improved as a result of receiving SG intervention. Furthermore, of the five studies examining comparable SG and 1-on-1 interventions, 79% of the students performed equally well from both interventions. Implications and several recommendations for future research are discussed.     

Childbirth and Alcohol Consumption Impact of Recent Childbirth on Alcohol Consumption

While the devastating effects of parental alcohol use on children’s health are well known, the specific impact of childbirth on parental alcohol consumption has rarely been examined in the general population. We sought to examine patterns of alcohol use associated with childbirth. Data were drawn from the US National Epidemiologic Survey on Alcohol and Related Conditions. We compared successively the characteristics of alcohol use among females living with a child under 1 year with (i) those of females not living with children under 1 year and (ii) those of females living with an older child. Mean daily ethanol intake was lower among females living with a child under 1 than among females either not living with children under 1 year (p?<?0.001) or living with an older child (p?<?0.01). Moreover, low-to-mild drinking frequencies fell among females living with a child under 1, compared with females either not living with children under 1 year (adjusted odds ratio (AOR)?=?0.56; 95% CI [0.40, 0.80] for at least once a month and AOR?=?0.40; 95% CI [0.27, 0.58] for less than once a month) or living with an older child (AOR?=?0.52; 95% CI [0.36, 0.75] for at least once a month and AOR?=?0.66, 95% CI [0.46, 0.94] for less than a month). No significant difference was found for males. Our study suggests that childbirth, as opposed to motherhood per se, reduces several (though not all) dimensions of alcohol consumption in females, but not in males.     

Safety Behavior After Extinction Triggers a Return of Threat Expectancy

Safety behavior is involved in the maintenance of anxiety disorders, presumably because it prevents the violation of negative expectancies. Recent research showed that safety behavior is resistant to fear extinction. This fear conditioning study investigated whether safety behavior after fear extinction triggers a return of fear in healthy participants. Participants learned that two stimuli (A and C) were followed by an aversive loud noise (“threat”), and one stimulus (B) was not. Participants then learned to use safety behavior that prevented the loud noise. Next, A and C were no longer followed by the loud noise, which typically led to extinction of threat expectancy. Safety behavior then became available again for C, but not for A and B. All participants used safety behavior on these C trials. In a final test phase, A, B, and C were presented once without the availability to use safety behavior. At each stimulus presentation, participants rated threat expectancy by indicating to what extent they expected that the loud noise would follow. Compared with the last extinction trial, threat expectancy increased for C in the test phase, whereas it did not increase for A and B. Hence, safety behavior after the extinction of classically conditioned fear caused a partial return of fear. The findings suggest that safety behavior may be involved in relapse after exposure-based therapy for anxiety disorders.     

You meta believe it

Because of the privileged place of beliefs in explaining behaviour, mismatch cases—in which agents sincerely claim to believe that p, but act in a way that is inconsistent with that belief—have attracted a great deal of attention. In this paper, I argue that some of these cases, at least, are at least partially explained by agents believing that they believe that p, while failing to believe that p. Agents in these cases do not believe that ~p; rather, they have an indistinct first‐order, beliefy, representation that p. The indistinctness of this first‐order representation provides the leeway for the inconsistency seen in their behaviour.     

Neither Fish nor Fowl: Implicit Attitudes as Patchy Endorsements

Implicit attitudes are mental states that appear sometimes to cause agents to act in ways that conflict with their considered beliefs. Implicit attitudes are usually held to be mere associations between representations. Recently, however, some philosophers have suggested that they are, or are very like, ordinary beliefs: they are apt to feature in properly inferential processing. This claim is important, in part because there is good reason to think that the vocabulary in which we make moral assessments of ourselves and of others is keyed to folk psychological concepts, like ‘belief’, and not to concepts that feature only in scientific psychology: if implicit attitudes are beliefs there is a prima facie case for thinking that they can serve as the basis for particular kinds of moral assessment. In this paper I argue that while implicit attitudes have propositional structure, their sensitivity and responsiveness to other mental representations is too patchy and fragmented for them to properly be considered beliefs. Instead, they are a sui generis kind of mental state, a state I dub patchy endorsements.
