The extent of Russell''s modal views

Russell has recently been held to have had a modal logic, a full modal theory and a view of naming that anticipates Kripke's intuitions on rigid designation. It is argued here that no such claims are warranted. While Russell was not altogether silent on matters modal, he did not advance an identifiable modal logic or anything more than a modest modal theory. His view of naming involves a notion of guaranteed reference. But what Kripke's intuitions about rigidity primarily pertain to is fixed reference, something demonstrably different.     

The extent and characteristics of driving anxiety

Research over the last two decades has resulted in improved understandings of the nature and characteristics of driving anxiety. However, we still do not know the extent of driving anxiety in the general population, as most studies have focused on clinical or vehicle accident samples, and the only population study is of older adults. The present study addressed this gap in knowledge using data from 441 people who responded to a survey sent to a random sample of 1500 adults recruited from the compulsory voting register in New Zealand. While 31% reported no driving anxiety, 52% endorsed mild driving anxiety and 16% reported moderate to severe driving anxiety. There were small but significant differences in the average age at which participants in these three groups started to learn to drive, but there were no differences in driving-related accidents and incidents over the past 12 months. Those with higher driving anxiety endorsed more anxiety about road rage, lower feelings of safety while driving, and more driving-related avoidance and negative cognitions than the less anxious participants. However, levels of helpseeking were low, and suggest the need to develop online self-help packages that are more accessible and acceptable to those experiencing driving anxiety.     

The psychological present

The present paper compares behavior-analytic and cognitive treatments of the concept of psychological history with regard to its role in current action. Both treatments take the position that the past bears some responsibility for the present, and are thereby obligated to find a means of actualizing the past in the present. Both do so by arguing that the past is brought to bear in the present via the organism. Although the arguments of the two positions differ on this issue, neither provides a complete account. An unconventional treatment of psychological history is proposed, the logic of which is exemplified in anthropological, biological, and psychological perspectives. The unconventional treatment in psychological perspective holds that (a) the organism's interaction with its environment, not the organism itself, changes with experience; and (b) the past interactions of an organism exist as, and only as, the present interactions of that organism. This solution to the problem of psychological history provides obligations and opportunities for analysis that are not available when the more conventional positions of cognitivism and behavior analysis are adopted.     

The extent of Panum's area and the human cortical magnification factor

The horizontal extent of Panum's fusional area was measured by means of a single-vertical-line stimulus placed at thirty-two locations throughout the peripheral visual field. These results were transformed by using known values of the human cortical magnification factor (CMF), and the hypothesis that variations in the magnitude of Panum's area may be accounted for by variations in the CMF was tested. It was found that the increase in Panum's area with increasing stimulus eccentricity correlates well with the CMF, but that variations in the extent of Panum's area as a function of angular position around the line of sight do not correspond well with the CMF.     

The Poggendorff Illusion and estimates of transverse extent.

The underestimation of transverse extent relative to longitudinal extent, in the Poggendorff Illusion, was tested by varying oblique line orientation, interparallel line distance, and presence or absence of obliques. 20 subjects made estimates of the transverse extent on both a longitudinal and transverse extent. The results indicated that, although underestimation was found for some stimulus conditions, overestimation was found for others. It was argued that even though presence of obliques affected judgmental error the longitudinal-transverse illusion could not form a basis for the Poggendorff Illusion.     

The extent to which viewers watch violence-containing programs

Content analysts have focused upon measures of physical violence leading or partially leading to injury and death, and have used these to assess the violence levels in programs. Critical analysts have recognized that the more violent programs, on these criteria, constitute a category of action adventure series of serials, as well as characterizing many one-off films. The audience does not consume these (or other) types of programs homogeneously; thus young teenagers have a higher rate of consumption of action adventure. Overall, in Britain, amount of viewing of action adventure as well as of violent films does not exceed one-fifth or one-sixth of the overall viewing diet per week, though in exceptional cases people may see as much as half their total viewing from this category. Apart from situational influences, evidence exists that personality attributes relate to amount of viewing of action adventure (not necessarily, and even probably not for their violent content). In fact it seems to be more timid people, lower on sensation seeking, higher on external locus of control, who view more action adventure; and these programs tend to be rated overall as of relatively low impact and attention value. Other studies indicate that higher violence content does not contribute toward larger audiences. Probably, therefore, violence-containing programs are viewed for their arousal-inducing and retribution-dealing attributes, by more timid rather than by more aggressive people.     

Commentary: The past and present of the future

Recent research on children's thinking about the future has taken multiple directions, many of which are illustrated in the contributions to this special issue. In this commentary the topic is discussed in the context of research on children's understanding of time, and some of the adaptive challenges of thinking about the future are considered. The studies in this issue show the emergence of some components of thinking about the future in early childhood. More research will be needed to illuminate abilities acquired at later ages and the representations and processes underlying humans’ thinking about the future.
