Face Recognition Across Viewpoint

by

Abstract

In two experiments we examined the ability of human observers to recognize faces from novel viewpoints. Previous work has indicated that there are marked declines in recognition performance when observers learn a particular view of a face and are asked to recognize the face from a novel viewpoint. We replicate these ndings and extend them in several ways. First, we replicate the well-known 3/4 view advantage for recognition and extend it to show that this advantage is stronger than would be expected simply due to the 3/4 view being the center of the learned views. In the second experiment, we found little evidence for advantageous transfer to a symmetric view of the other side of the face, in all cases, observers were much better at recognizing a face from the side learned. Third, we extended past results to explore the consistency of face recognizability for individual faces across di erent views and view transfer conditions. We found only a modest relationship between the...

The Accuracy Of Eyewitness Identifications

THE ACCURACY OF EYEWITNESS IDENTIFICATIONS

Archival Studies Show that Mistaken Identification is the Primary Cause of Erroneous Convictions. Several legal scholars, beginning with Borchard (1932), have studied the causes of mistaken identification in over 1,000 criminal cases (see also Brandon & Davies, 1973; Frank & Frank, 1957; Huff, 1987; Huff, Rattner & Sagarin, 1986). Huff (1987) readily concludes, on the basis of studying the 500 cases of erroneous conviction that he identified, that the single leading cause of mistaken conviction was erroneous eyewitness identification of the defendants. He states that eyewitness error was involved in nearly 60% of the cases he studied. Rattner’s (1988) analysis of 205 cases of wrongful conviction demonstrated that over 50% were attributable to mistaken identifications (also see Borchard, 1932). In a more recent study, the figure is as high as 79%. (Brandon Garrett, Judging Innocence, Columbia Law Review). This rate is all the more remarkable given that some commentators estimate that eyewitness identifications are prominent in only 5% of trials (Loh, 1981)...

Prohibited Persons Notice Form and Power of Attorney for Firearms Relinquishment

by

Effective January 1, 2002, Senate Bill 950 (Chapter 944, Statutes of 2001) establishes a provision to provide a person legally prohibited from owning/possessing firearms with a notification form. The intent of the notification form is to ensure that persons who become firearms prohibited are promptly notified to immediately transfer or dispose of any illegally owned/possessed firearms. Failure of prohibited persons to divest themselves of any and all firearms could result in criminal sanctions.

Pursuant to Penal Code (PC) Sections 12021(a)(b) and (c) persons are deemed firearms prohibited if they are within any one of the categories as follows:

• Convicted of a felony;
• Addicted to the use of narcotics;
• Certified by a juvenile court for prosecution as an adult in an adult court pursuant to Section 707 of the Welfare and Institutions Code (WIC);
• Convicted of a misdemeanor enumerated in PC Sections 12001.6 and 12021(c)(1)
• Admitted to a mental health facility pursuant to 8100, and 8103 WIC; OR:

Face Matching Under Time Pressure and Task Demands

by

Abstract

Understanding how people recognize and match faces is important in many real-world situations, including policing, military, security and retail environments. We investigate the effects of time pressure and additional task demands on face matching performance. In a 2x2 factorial design—varying whether there was high or low time pressure, and whether or not an ad- ditional task had to be completed—participants were asked to judge whether each of a series of face image pairs were of the same person. Large individual differences were observed. Recall was higher than precision, and performance worsened under high time pressure with the additional task. Learning effects within conditions were observed, and response times were generally independent of the decisions made. Some implications of these findings for applied environments are discussed.

Introduction

Face matching is the process of verfiying the equivalence of two or more people on the basis of their fa- cial characteristics. It involves visually perceiving a face, and...

Using Quantitative and Qualitative Models to Forecast Instability

by

Introduction

There is a strong tendency in both government and private enterprise to seek out the “best” method of doing a task and then rely on that method. In manufacturing or policy design, this approach makes agreat deal of sense why use a mix of best and second best methods if one approach has been demonstrated to be clearly superior? In forecasting violent conflict, the traditional method has been to rely on expert analysis of individual countries or regions, drawing on the knowledge of policy professionals and academics who have worked on the country or region in question for a substantial period of time. Such qualitative analysis generally rests on the expert’s subjective analysis of a mix of sources, including news reportage and other media sources, other open-source data, and embassy and intelligence reports. Recently, however, a number of quantitative models, based on objective analysis of open-source data, have been offered to analysts as a supplement to their traditional analysis. Notable examples are the...

Trimipramine

by

Description

Tricyclic antidepressants act to change the balance of naturally occurring chemicals in the brain that regulate the transmission of nerve impulses between cells. Trimipramine acts primarily to increase the concentration of norepinephrine and serotonin (both chemicals that stimulate nerve cells) and, to a lesser extent, to block the action of another brain chemical, acetylcholine. Trimipramine shares most of the properties of other tricyclic antidepressants, such as amitriptyline , amoxapine , clomipramine , desipramine , imipramine , nortriptyline , and protriptyline . Studies comparing trimipramine with these other drugs have shown that trimipramine is no more or less effective than other antidepressants of its type. Its choice for treatment is as much a function of physician preference as any other factor. antidepressants, appear slowly. Maximum benefit is often not evident for at least two weeks after starting the drug. People taking trimipramine should be aware of this and continue taking the drug as directed even if they do not see immediate improvement.

Haloperidol

by

Haldol is the brand name for haloperidol, an anti-psychotic medicine used to treat mental and mood disorders, including schizophrenia and acute psychosis.

It is often used in emergency room psychiatric situations. It helps reduce aggression, negative thoughts, and the desire to harm someone or oneself.

It can also help to reduce hallucinations, as well as to treat uncontrolled outbursts related to Tourette's disorder, and it can be used for short periods of time for people who have acute agitation.

In children, Haldol may be used for severe behavior problems including hyperactivity or aggression.

Haloperidol was developed by a Belgian company in 1958, and approved by the Food and Drug Administration (FDA) in 1967. McNeil Laboratories marketed the drug under the brand name Haldol. The tablet forms are now available only generically.

Haldol Warnings
Haldol may make you dizzy, so do not drive or operate machinery until you know how it affects you. Do not drink alcohol and use Haldol.

Carbamazepine

by

Tegretol suspension in combination with liquid chlorpromazine or thioridazine results in precipitate formation, and, in the case of chlorpromazine, there has been a report of a patient passing an orange rubbery precipitate in the stool following coadministration of the two drugs (see PRECAUTIONS: DRUG INTERACTIONS). Because the extent to which this occurs with other liquid medications is not known, Tegretol suspension should not be administered simultaneously with other liquid medications or diluents.

Monitoring of blood levels has increased the efficacy and safety of anticonvulsants (see PRECAUTIONS, Laboratory Tests). Dosage should be adjusted to the needs of the individual patient. A low initial daily dosage with a gradual increase is advised. As soon as adequate control is achieved, the dosage may be reduced very gradually to the minimum effective level. Medication should be taken with meals.

Since a given dose of Tegretol suspension will produce higher peak levels than the same dose given as the tablet, it is recommended to

Divisions of the Nervous System

by

The nervous system has two main divisions: the central nervous system (CNS) and the peripheral nervous system (PNS) (Figure31). The CNS is the body’s control center, consisting of the brain and spinal cord. The brain is responsible for consciousness; its functions include perception, emotion, memory, thought, and language. The lower parts of the brain are also responsible for some unconscious functions, such as regulation of the endocrine (hormonal) and cardiovascular systems. The spinal cord is responsible for simple reflexes; it also serves as a pathway between the brain and the PNS.

The PNS is the body’s communication network; it includes the nerves and sense organs. Nerves are bundles of fibers that carry signals to and from the CNS. Motor nerves carry commands from the CNS to muscles and glands; sensory nerves carry input from sense organs (receptors) to the CNS. Different kinds of sensory receptors respond to differen..t

Classifying Faces by Race: The Structure of Face Categories

by

Although face perception is usually studied from the standpoint of our amazing ability to differentiate a large number of faces, representations of face categories are also important. The process of categorizing individual faces has a number of implications both for general models of classification and for understanding face identification. The focus here is on the apparently paradoxical finding that participants are faster to classify faces they have difficulty recognizing. In the present case, this means that White participants classify Black or Asian faces faster than White faces (Levin, 1989; Valentine & Endo, 1992). In attempting to understand facilitated classification of cross-race faces (hereinafter referred to as the CR [cross-race] classification advantage), the present research considers explanations for the CR classification advantage as they relate to the basic structure of face categories, both in terms of discrimination between categories and in terms of their internal structure. Three explanations for the CR classification advantage are tested here. The first, stemming from Valentine's (1991) multidimensional space framework, places the advantage in
