What I Would Use As The Icebreaker Slide

This study has helped in the understanding of criminal behaviour as children learn through imitation and the environment which they grow up in have an effect on their behaviour. If a child has been brought up around abuse, criminal activity or consistent aggression then the child is most likely to offend by imitating their role model which could be a parent, sibling or even just a role model which they look up to.

            According to Sacco and Kennedy (2008, pg.116) the recent biological explanations are different compared to the earlier biological explanations in several ways. The recent explanation is concentrated more on genetic factors.  Additionally, “the impact of biological factors is mediated by the social environment” (Sacco & Kennedy, 2008, pg.116). There are four main approaches that have overcome the weaknesses of the earlier biological explanations: the general pedigree studies, twin studies, adoption studies, and karyotype studies. The general pedigree studies involve people that are related to one another to see if they behave in similar ways. These studies show that people who manifest criminal behaviour are more likely to have offspring that do the same (Cartwright, 2009).  However, evidence for the causality of criminal behaviour by genetics is lacking. Other factors that are environmental and accumulative should be considered (Cartwright, 2009). Twin studies on the other hand, avoid the problem that the pedigree studies face. In twin studies, monozygotic (MZ) twins and dizygotic (DZ) twins are tested. According to Fishbein (1990, pg. 54), MZ twins inherit one hundred percent of their parents genes whereas DZ twins only inherit fifty percent. Studies have shown that if an MZ is involved in a criminal behavior, the other

Table 3-1 examines the correlations between selected characteristics for the identical twins separated at birth and the twins raised together. When compared to each other, they both have very similar brain wave activity, blood pressure and heart rate in the physiological characteristics. The Raven intelligence test was very similar, but the WAIS IQ displayed a bit of difference when compared to the other comparisons made. Personality wise, they typically had similar personalities at the same rate as twins raised together. Psychological interests were off a little bit, but still very similar. The twins that were separated at birth had less similar psychological interests compared to the twins

Genetics and behavior relations has been a controversial topic for several years, however, as time has passed so has the demand for proof or disproof of the relationship. One of the most important reasons for the need to define this relationship is to uncover the truths behind violent or delinquent behavior. Also, it is important that we can weed out people who make false claims that their genes are responsible for their actions in order for us to appropriately distribute penalties or treatment. Another reason is that if we do find truths to these claims we can find ways to treat these behaviors for better outcomes. Though many studies have been conducted to reveal associations, more research is yet to be done that explores all connections and detailed backgrounds of those involved in the studies. To begin validating our theories, we must use genotyping, which is the comparison of an individual’s genetic make-up through exploration of their DNA sequence then comparing it to the DNA sequence of another individual or a reference sample. Utilizing genotyping, we are able to view the alleles an individual inherited from their parents (slide 4).

The primary risk factors for criminal behavior majorly come into play in the early years of a person’s life.

Twin studies are a mainstay of the nature verse nurture debate because they allow researchers to conduct “natural experiments” on human beings. When researchers try to determine the relative importance of genetics and environment with regard to a certain condition, they have a hard time because they cannot generally get people with the same genes. This is where twin studies come in. Twins studies are part of the method used in behaviour genetics, which includes all data that are genetically informative. E.g. siblings, adoptees, pedigree data etc. Researchers use this method to estimate the heritability of traits and to quantify the effect of a person 's shared environment (family) and unique environment (the individual events that shape a life) on a trait.

The Minnesota Twin Registry started in 1983 and its goal was to establish a registry of all twins born in Minnesota from 1936 to 1955 to be used for psychological research.., T.J. Bouchard, working in conjunction with the University of Minnesota, started exploring the similarities and differences in characteristics like personality, career interests, and a variety of personal interests between identical twins who were reared apart. Research was conducted on twins from all over the world. The Minnesota Twin study gave scientists a new insight of the role of nature vs. nurture on human development and personality; it was the hope that twin studies would be able to tie genes to specific behaviors. From the study, we understand that twins who were separated at birth and raised in different families

“In 1993, Moffitt states that manifestations of antisocial behavior emerge very early in the life course and remain present thereafter, suggesting childhood behaviors are links to adult criminality.” This notes the importance of exploring why these antisocial tendencies come to light in adolescence, in order to prevent future criminality. Thus, researching the differences and similarities between conduct disorder (CD), antisocial personality disorder (ASPD), and their rehabilitation can influence the likelihood of future crime, in addition to studying future criminality based on gender, individuality, and the effectivity of treatment in relation to CD.

Evidence indicates that genetic factors may play a role in development of disruptive behavior disorders (Hansell & Damour, 2005). A biological structure of an infant’s brain has preposition genes and chemical responses to develop into an adult (Perry, 2002). Disorders in lifespan development are not biologically set to occur (Dombeck, 2010). Issues’ dealing with environment, education, and way of life has made changes in developments, childhood behavior keeps a child on a continuum between normal and abnormal behavior (Hansell & Damour, 2005). Several disorders currently exist in the Diagnostic and Statistical Manual (DSM-IV-TR) because studies on children, adolescent, and young adult disorders evolved from DSM-II (Hansell & Damour, 2005).

Detail ways/reasons that the icebreaker was successful toward meeting goal and why. The icebreaker I chose forced all the members to be very active as they had to perform hand signals and foot motions to alert other people without letting the person in the middle know who has the sign. Furthermore, people had to purposefully move around in two ways. One was to prevent the attention the middle person paid to each individual person. The last is to play the game as it is passing the sign from one member to the other.

In this study, they are used several type of method, one of the technique is used two or more test instrument to ensure the adequate coverage, for example the participants were given a battery of personality and mental ability tests, interest and value inventories and psychomotor tests. In addition, separate of examiners administer the IQ test, life history interview, psychiatric interview and sexual life history interview. The twin also complete questionnaire independently under the constant supervision of the staff members. Twin studies are valuable to researchers because identical twins share 100% of their genes and fraternal twins share, on average, 50% of their genes. Both identical and fraternal twins share certain aspects of their environment (e.g. religious practices in the home). This allows researchers to estimate the heritability of certain traits. Participants are asked about academic ability, personality, and interests; family and social relationships; mental and physical health; physiological measurements. Of interest to researchers are prevalence of psychopathology, substance

Another study that has been done was with separated twins. Each twin was raised in a completely different environment than the other. Genetically, they were both identical in every way, but the environment that they were raised in was very different. One twin was raised in a very hostile setting and slowly became violent as an adult while the other twin was

One factor that influences the likelihood of criminal behavior involves a person’s genetics. Certain inherited behaviors can lead people to be more likely to have criminal behaviors. Stated in the article "The Criminal Mind,” Arian Raine explains, “More than 100 studies of twins and adopted children have confirmed that about half of the variance in aggressive and antisocial behavior can be attributed to genetics.” (Raine). Aggressive and antisocial behaviors are found in many criminals. Research proves that these behaviors can be due to genetics, and this makes these behaviors a genetic influence to criminal behavior. Additionally, anybody can be a criminal, but gender plays a role in their chances as well. In the article “Born

Is how aggressive an individual is determined only by his or her genes? Whether psychological and behavioral traits are purely determined by genetics, solely influenced by socialization, or a combination of both has been a highly debated topic within the field of psychology known as the “nature-nurture issue.” Today, although still disputed, a good number of psychologists and other scientists concur that genetics and the environment mutually influence and intermingle with one another (Myers, 2015). We can partially credit this fizzling-out of the nature-nurture debate to the discoveries made in twin studies. Twin studies are used to help delineate the genetic components of behavior and the socially and culturally influenced components (Myers, 2015). This type of study enables researchers to examine the extent to which genetics and environment have an effect on the development of traits and behavior. For example, in lecture, we learned that a common and natural experiment used in twin studies is to examine a set of twins who grew up in the same household and a set twins who grew up in separate households (K.W. Brown, personal communication, August 29, 2017).
