Truth,Ramsification, and the Pluralist's Revenge

Functionalists about truth employ Ramsification to produce an implicit definition of the theoretical term true, but doing so requires determining that the theory introducing that term is itself true. A variety of putative dissolutions to this problem of epistemic circularity are shown to be unsatisfactory. One solution is offered on functionalists' behalf, though it has the upshot that they must tread on their anti-pluralist commitments.     

Posttraumatic stress symptoms following childbirth and mothers' perceptions of their infants

Postpartum psychological distress can adversely affect the early mother–infant relationship; however, this has not been investigated in relation to posttraumatic stress disorder (PTSD) following childbirth. This article explores whether PTSD symptoms relating to labor and delivery are associated with mothers' early perceptions of their infant. Using labor and childbirth as the stressor criterion, 211 women were assessed at 6 weeks' postpartum for symptoms of intrusions, avoidance, and hyperarousal. Their perceptions of their infants, of mother‐to‐infant attachment, and infant behavioral characteristics also were evaluated. In sum, 3.8% of the women fulfilled full diagnostic criteria, and a further 21.3% reported clinically significant symptoms on at least one dimension of PTSD. Those meeting full or partial criteria perceived their attachment relationships to be significantly less optimal and reported more negative maternal representations in terms of their infants being less warm and more invasive. They also rated them as being temperamentally more difficult, prone to distress, and less easy to soothe. However, when the effects of depression were partialled, only the effect for perceived warmth remained. Posttraumatic stress symptoms relating to labor and delivery may adversely influence maternal perceptions of infants, with potentially adverse implications for the developing mother–infant relationship. The overlap with depressive symptoms requires further exploration.     

Recognition and context memory for faces from own and other ethnic groups: A remember-know investigation

People are more accurate at recognizing faces from their own ethnic group than at recognizing faces from other ethnic groups. This other-ethnicity effect (OEE) in recognition may be produced by a deficit in recollective memory for other-ethnicity faces. In a single study, White and Black participants saw White and Black faces presented within several different visual contexts. The participants were then given an old/new recognition task. Old responses were followed by remember-know-guess judgments and context judgments. Own-ethnicity faces were recognized more accurately, were given more remember responses, and produced more accurate context judgments than did other-ethnicity faces. These results are discussed in a dual-process framework, and implications for eyewitness memory are considered.     

How a “Reasonable Doubt” Instruction Affects Decisions of Guilt

Jurors are instructed to render a guilty verdict if they feel the defendant is guilty beyond a reasonable doubt. The jury is often told that this does not mean an absolute certainty of guilt and that even if it were possible to imagine a scenario in which the defendant is innocent, a guilty verdict may still be appropriate. Here, participants read a case summary. They were either told to say that the defendant was guilty if they believed in guilt beyond a reasonable doubt or were given more detailed instruction stressing that they did not have to be absolutely certain of guilt to give a guilty verdict. In Experiment 1, participants provided “think-aloud” protocols. Content analysis revealed that those who were given this instruction often used the phrase reasonable doubt to justify their guilty verdicts by saying that although they were not certain of the defendant's guilt, their belief exceeded the reasonable doubt threshold. None of the participants in the control group did this. Experiment 2 was designed to test if the instruction affected belief in guilt and the reasonable doubt threshold quantitatively. The instruction affected both people's belief in guilt and the threshold that they used to define reasonable doubt. The implied values for reasonable doubt were 63% for those who received the instruction and 77% for the control group. Implications for jury decision making are discussed.
