Evaluation and recall of evidence: Authoritarianism and the Patty Hearst case

By using the Patricia Hearst case as the stimulus material, two experiments were conducted to examine the relationship between authoritarianism and recall of evidence. In Experiment I it was found that high authoritarians recall more prosecution evidence than defense evidence. This was not the case for the low authoritarians. Results concerning the hypothesis that high authoritarians would recall more character information than low authoritarians were equivocal. In Experiment II a trend indicating that high authoritarians draw more direct inferences from incriminating evidence than do low authoritarians or an attorney was obtained. The results are discussed in terms of previous findings, authoritarian theory, and characteristics of the Patricia Hearst case.     

Flavor-illness aversions: potentiation of odor by taste is disrupted by application of novocaine into amygdala

Taste and odor have different properties in toxiphobic conditioning. When each is used alone, taste becomes aversive when followed by immediate or delayed poison, while odor becomes aversive only if followed by immediate poison. However, if odor and taste are presented as a compound and followed by delayed poison, then odor does become aversive when tested alone. It is as if taste has potentiated the odor signal. Several experiments assessed the role of the amygdala in this potentiation effect by anesthetizing the amygdala with 10% novocaine. Novocaine applied 30 min before presentation (Pre-CS) of an odor-taste compound disrupted the potentiated odor aversion but not the taste aversion. In contrast, novocaine applied 1 min after the compound odor-taste or 1 min prior to LiCl poison did not dissociate odor and taste aversions; both odor and taste aversions were facilitated. Novocaine applied 30 min before an odor alone also disrupted an odor aversion induced by immediate LiCl. But identical treatment did not disrupt odor avoidance conditioned by immediate foot-shock, suggesting that amygdala anesthesia does not simply produce anosmia. Pre-CS novocaine treatment also disrupted flavor neophobia prior to conditioning. The results suggest that novocaine applied to the amygdala disrupts the integration of odor with taste and illness during toxiphobic conditioning.     

Reading Rates and Digit Span in Bilinguals: The Superiority of Mother Tongue

Several studies have shown a negative linear relationship between speech rate and memory span. This relationship has implications for bilingual studies, as span could be larger in a bilingual's secondary language provided that pronunciation rate is faster than in the mother language. The purpose of this study was to investigate the effects of digit word length on digit span in bilinguals. Experiment 1 tested the effects of digit syllable length on speech rate in five different bilingual groups. Results revealed that digit-reading rates were significantly faster in all mother languages. Experiment 2 examined more closely the correspondence between speech rate and digit span with Portuguese-English bilinguals. Results showed that digit-reading rates were faster and digit span larger in the mother language even if the mean number of syllables per digit was higher. The superiority of mother tongue was discussed according to the view that digits are subject to massive practice in one's native language with a strong tendency to be abbreviated, thus reducing its spoken duration.     

On the irreducibility of the will

This paper criticizes the thesis that intending to do something is reducible to some combination of beliefs and desires. Against Audi's recent formulation of such a view I offer as counterexample a case wherein an agent who wants and expects to V has not yet decided whether to V and hence does not yet intend to. I try to show that whereas belief that one will V is not necessary for intending to V, as illustrated in cases of desperate attempts to V, one cannot intend to V without preferring to V (rather than not V) and thus one cannot intend to V without, in some sense, wanting to V (at least wanting it in preference to not V-ing). The connection of one's intentions with one's objectives, attempts, plans, and hopes is briefly treated, and some influential work by Davidson is criticized.     

Some remarks on “ambiguity” and “perceptual processes”

A paper by Bever, Garrett, and Hurtig on the perception of ambiguous sentences is analyzed in terms of (1) the explanation offered for the experimental findings, (2) the linguistic theory underlying the experiment, and (3) the characteristics of the stimuli utilized. It is concluded that Bever, Garrett, and Hurtig's findings are open to serious question, particularly because of multiple deficiencies in the design of the experiment.     

Improving Delivery Behaviors During Exposure for Pediatric OCD: A Multiple Baseline Training Trial With Community Therapists

This study tested whether a new training tool, the Exposure Guide (EG), improved in-session therapist behaviors (i.e., indicators of quality) that have been associated with youth outcomes in prior clinical trials of exposure therapy. Six therapists at a community mental health agency (CMHA) provided exposure therapy for 8 youth with obsessive–compulsive disorder (OCD). Using a nonconcurrent multiple baseline design with random assignment to baseline lengths of 6 to 16 weeks, therapists received gold-standard exposure therapy training with weekly consultation (baseline phase) followed by addition of EG training and feedback (intervention phase). The primary outcome was therapist behavior during in-session exposures, observed weekly using a validated coding system. Therapist behavior was evaluated in relation to a priori benchmarks derived from clinical trials. Additional outcomes included training feasibility/acceptability, therapist response to case vignettes and beliefs about exposure, and independent evaluator-rated clinical outcomes. Three therapists reached behavior benchmarks only during the EG (intervention) phase. Two therapists met benchmarks during the baseline phase; one of these subsequently moved away from benchmarks but met them again after starting the EG phase. Across all therapists, the percentage of weeks meeting benchmarks was significantly higher during the EG phase (86.4%) vs. the baseline phase (53.2%). Youth participants experienced significant improvement in OCD symptoms and global illness severity from pre- to posttreatment. Results provide initial evidence that adding the EG to gold-standard training can change in-session therapist behaviors in a CMHA setting.     

Réflexions critiques sur les notions d’abolition et d’altération de la faculté à discerner

Inasmuch as the constitution of the mens rea of any offence remains suspended to its integrity, the capacity for discernment represents a condition of accountability whose definition responds to issues that are as much technical – with respect to psychiatric and psychological penal expertise – as they are theoretical – with respect to our conception of criminal responsibility and the psychological prerequisites that underlie it. Now, the fact is that since its introduction in 1992 with article 122–1 of the Penal Code, this notion of discernment is characterized by a certain conceptual inconsistency, giving rise to a damaging plurality of meanings making the verb discern the condensed version of a heterogeneous network of distinct psychological functions. The polysemic term of discernment thus gives rise to a fundamental indetermination as to the nature of the faculty that must be examined in order to decide on its abolition or its preservation at the moment of the act. This is not without favouring the appearance and persistence of arbitrary interpretations, and consequently discordant expert conclusions. Even more problematic, however, is the idea of an alteration of discernment, given the irreducible discrepancy between the continuous nature of an alteration and the discontinuous nature of the conclusion to which the agent is subject, in that the legal demand requires a decision – in a discretization of what is continuous – between the presence and absence of something that is lacking. We will in fact show in what way this concept of alteration as it applies to discernment tends to be either meaningless, or redundant – and therefore useless – in relation to that of abolition. So much so that the only conceivable solution to maintain a certain gradation of degrees of non-accountability seems to consist in having to specify the different types of abolition of discernment potentially observed, and then to propose a hierarchization according to their greater or lesser compatibility with the conservation of a criminal responsibility. .     

Cerebral blood flow in 5‐ to 8‐month‐olds: Regional tissue maturity is associated with infant affect

Infancy is marked by rapid neural and emotional development. The relation between brain function and emotion in infancy, however, is not well understood. Methods for measuring brain function predominantly rely on the BOLD signal; however, interpretation of the BOLD signal in infancy is challenging because the neuronal‐hemodynamic relation is immature. Regional cerebral blood flow (rCBF) provides a context for the infant BOLD signal and can yield insight into the developmental maturity of brain regions that may support affective behaviors. This study aims to elucidate the relations among rCBF, age, and emotion in infancy. One hundred and seven mothers reported their infants' (infant age M ± SD = 6.14 ± 0.51 months) temperament. A subsample of infants completed MRI scans, 38 of whom produced usable perfusion MRI during natural sleep to quantify rCBF. Mother‐infant dyads completed the repeated Still‐Face Paradigm, from which infant affect reactivity and recovery to stress were quantified. We tested associations of infant age at scan, temperament factor scores, and observed affect reactivity and recovery with voxel‐wise rCBF. Infant age was positively associated with CBF in nearly all voxels, with peaks located in sensory cortices and the ventral prefrontal cortex, supporting the formulation that rCBF is an indicator of tissue maturity. Temperamental Negative Affect and recovery of positive affect following a stressor were positively associated with rCBF in several cortical and subcortical limbic regions, including the orbitofrontal cortex and inferior frontal gyrus. This finding yields insight into the nature of affective neurodevelopment during infancy. Specifically, infants with relatively increased prefrontal cortex maturity may evidence a disposition toward greater negative affect and negative reactivity in their daily lives yet show better recovery of positive affect following a social stressor.

Influence of individual differences in working memory on the continued influence effect of misinformation

ABSTRACT

Misinformation often continues to influence people’s cognition even after being retracted (the continued influence effect of misinformation, CIE). The current research aimed to investigate whether the individual differences in the central executive function of WM and updating could influence the CIE of misinformation with varying relevance. The results showed that the individual differences in central executive function could significantly affect the CIE, especially for the high-relevant misinformation. While the individual differences in the updating ability had a weaker impact on the CIE in general and only negatively related to the CIE for the low-relevant misinformation. The study extends the understanding of the relationship between individual differences and the CIE from previous studies, which is in line with the mental-model-updating hypothesis, and offers a preliminary clue for identifying the persons vulnerable to the CIE of misinformation in the real world.
